How to stop marine stray current corrosion in 3 steps.

Link to Home page How to conquer corrosion in 3 steps

Step 1: Understand:

Marine stray current corrosion is caused by fault/s on your boat. SeaBis measures that stray current with extreme accuracy.  To eliminate the cause  switch off equipments until SeaBis indicates Normal. Now follow How To Stop Corrosion, supplied with SeaBis Master System.

SeaBis is an easily installed 3 wire traffic light system, support included.

Marine stray current explanation

Assuming you are sitting at your desk and the light is on. Now leave the light on. So you do not burn your hands, use a rag to remove the light. Voltage via the switch is still applied.  Now no current flows through the light so it ceases to deteriorate. Measuring voltage will show no change.  Measuring current will immediately show current is zero. SeaBis is the only system to eliminate the CAUSE of corrosion, World-wide. Now stop marine stray current with How To Stop Corrosion using SeaBis indications to correct the CAUSE/s. Or contact us.

Step 2: Identify:
Use SeaBis System to stop marine stray current

Connect SeaBis brown to battery positive, blue to battery negative.  Then green / yellow current sense to metal hull or engine body.  Make good connections with no paint, oil or grease. SeaBis indicates the ability of marine stray current to create corrosion. Now use How to Prevent Corrosion to stop marine stray current and complete correction of CAUSE.

Marine corrosion caused by stray current electrolysis eliminated
To identify the CAUSE, switch off circuits until SeaBis indicates Normal

How identify the CAUSE

Now switch off circuits until SeaBis indicates Normal (green).  The last circuit switched off was the cause.  It now has no power so is easily identified. How To Prevent Corrosion contains full instructions.  Support is included.

Step 3: Eliminate:
How to repair stray current CAUSE

SeaBis Master includes How To Stop Corrosion.  It details process, typical causes and their repair.  Free support value AU$80 or 1/2 hour on line, is included.

Keep SeaBis connected

Corrosion is generated by stray current caused by water in navigation lights, failed antenna, new equipment and carbon build up.  Now you are immediately warned you can stop  corrosion immediately.

Engines do not have to cause stray current

Recreational and some commercial engines are used less than 200 hours per year. A switch or solenoid can prevent 97% of the CAUSE of corrosion. The type of switch or solenoid and installation depends of your engine and SeaBis results.  Contact us and we will advise type and installation.  So installing a switch or modified solenoid will stop stray current – corrosion while engine is off.  The engine and solenoid are on less than 3 % of the time so resulting corrosion will be less than 3%.  Contact us with SeaBis indications and boat description before using this procedure.  If engine ON hours are greater than  200 hours per year then engine use is commercial so contact us with SeaBis indications.

Ongoing support

There will be times when stray current causes an other than Normal (green) and corrosion is ongoing.  Contact us and we will assist you. Updates to How To Prevent Corrosion will be emailed to you.

FAQ Frequently Asked Questions:

Explanation – the original cause of electrolysis:

 The cause of corrosive current is the battery ”0” volts terminal. In Kelvin Absolute Law terms (see Wikipedia) is actually at minus 12 volts for a 12 volt battery (24 for 24 volt battery). The metal contains electrons which are negatively charged. So the two negatives repel each other causing electrolysis to dissolve your metal into particles. The Earth is at +1.2 volts so attracts those particles. So your metal corrodes to the Earth. The solution is to use SeaBis to eliminate the cause.
See: Wikipedia electrolysis. Note DC (battery) power – the Apparatus power leads are red and black, and first paragraph specifically states DC, not AC(mains or shore power). 

Causes – not true:

 AC – Mains / shore / inverter power. AC current (power) cannot cause electrolysis as it changes direction every half cycle / Hertz.

 So IF it takes off a metal particle in the first half cycle it will replace it in the second half cycle.

 AC cannot cause electrolysis – it is impossible.

 Understand the real cause then eliminate it.

 DC (battery) current flows in the same direction, permanently.

 So will continually dissolve your metal. 24 hours every day of the year. With the negative only connected it will conduct to the Earth.

 Eliminate the CAUSE by using SeaBis Master and booklet supplied with SeaBis: How To Stop Corrosion.

 Is there DC – direct or battery current in AC?

 Please read the specification on your electric kettle / pot / hotplate. There will be no DC entry.

 If there were DC in the AC the electric kettle / pot / hotplate would attempt to draw in infinite current and burn out in a few seconds. As would every appliance in your country.

 Reference Wikipedia:- DC does not create Back EMF (Counter-electromotive force) so there is no resistance to DC current flow. DC current would attempt infinity.

 We must be correct: We guarantee

 to eliminate ALL CAUSES of electrolysis for 8 years using enclosed booklet: How To Stop Corrosion

 How to stop corrosion: the reason we supply a 8 year money back guarantee is we are 100% correct. Current through damp to wet metal to Earth is eliminated, permanently.

 That means no electrolysis, permanently.

 What is SeaBis?

 SeaBis is an electronic device with How To Stop Corrosion that WILL 100% and permanently stop electrolysis:

 Use the SeaBis System to identify then eliminate the leaking stray electrical current that is the direct cause.

 Permanently. No hull / metal penetration / additional coating or plating. The stray current SOURCE is eliminated.

 The benefits of using SeaBis – Use How To Stop Corrosion to eliminate the CAUSE.

 SeaBis shows the invisible electrolysis current that will cause corrosion in real time.

 There is no need to slip the vessel to see the anodes eaten away because SeaBis will be showing a warning light instantaneously.

 Better yet the SeaBis units Normal – green light is lit continuously with absolute peace of mind that the vessel is free of the stray current that will cause corrosion.

 How to stop corrosion completes elimination of ALL CAUSES.

 Stray current causes electrolysis that is the cause of 97% of all corrosion.

 Electrolysis is caused by DC (battery) current ONLY. The MAIN source of stray current that causes electrolysis is the vessels’ own battery bank. ALL CAUSES are eliminated by SeaBis System. 

 Stop electrolysis then rust and galvanic corrosion are easy to eliminate. The paint, coatings and anodes will not be destroyed by electrolysis.

 Your engine and hull will not be dissolved and anodes can protect your metal from galvanic corrosion as designed.

 SeaBis may be used with battery clips and moved battery bank to battery bank to eliminate all permanent causes. Intermittent and new causes require SeaBis be permanently installed.

 

Why does SeaBis succeed when a multi meter / test bulb-lamp / 1/2 cell must fail?

 The technical reason:

 Measurements must be used with everything at full power and at applied voltage (12 or 24 volts) without a limit in the measuring device and an extremely high current sensitivity. That device must have no effect on the circuit to be measured. SeaBis Master complies. Multi-meters measure at 1 volt at 1 millionth of an amp so have a error probability of greater than 1,000:1. In addition they alter the circuit under test. So multi-meters do not comply.

 Using a multimeter on amps is worse

and has resulted in death from acid burns caused by the multi meter shorting the battery and it exploding, on fire, hydrochloric acid over you.

 Test lamps are one million times insensitive. 1/2 cell, as a multimeter or test lamp measures voltage so can only deceive you.

  Stray current causes electrolysis. That is why I developed SeaBis. SeaBis measures current, accurately and safely. It separates the various types and levels of current so you know if your vessel is safe from electrolysis. SeaBis indicates the degree of risk so you can time your repair and if excessive AC in your DC can damage your batteries or electronics. How To Stop Corrosion completes the elimination of ALL causes. Permanently.

 In doubt? Ask any manufacturing jeweler

how he plates gold onto base ring. The gold is your damp too wet marine engine / hull and the base (jewelry-ring) is the Earth.

 Why do small to medium aircraft get electrolysis?

 Clouds have greater than 10% humidity. The air around aircraft, in clouds, contains more than the tolerance level of 10% humidity.
 Any metal in contact with the Earth, even remotely thru the air, passes stray current to the Earth so causing electrolysis.

 Large aircraft are correctly insulated so do not get electrolysis.

 SeaBis Master with How to stop corrosion completes elimination of ALL CAUSES.

 Stray current causes electrolysis that is the cause of 98% of all corrosion.

 Electrolysis is caused by DC (battery) current ONLY. The MAIN source of stray current that causes electrolysis is the vessels’ own battery bank. ALL CAUSES are eliminated by SeaBis System. 

 Stop electrolysis then rust and galvanic corrosion are easy to eliminate. The paint, coatings and anodes will not be destroyed by electrolysis.

 Your engine and hull will not be dissolved and anodes can protect your metal from galvanic corrosion as designed.

 SeaBis may be used with battery clips and moved battery bank to battery bank to eliminate all permanent causes. Intermittent and new causes require SeaBis be permanently installed.

  Electrolysis elimination 97% calculation:

Non commercial vessels use their engine/s less than 200 hours per year.

 There are 8,400 hours in a year so 200 hours divided 8,400 equals 2.38 percent of corrosion cause remaining, or contact me: [email protected].

 When SeaBis indicates NORMAL on all battery banks excluding engine we can supply a modified solenoid to keep engine electrolysis below 3%.
 In commercial use the engine ON hours will exceed 200 per year so full elimination of all causes is essential. We will guide you through, no matter the use.

 Why do small to medium trucks, planes and some vessels suffer from electrolysis when the larger do not?

 Larger trucks, planes and some professional vessels are correctly insulated. That will be the result of SeaBis Master and How to Stop Corrosion.

 

Link to Conquer corrosion in 3 steps

Proof we are correct Wikipedia

To fix, stop and prevent corrosion and we must:

1. Understand the CAUSE – usually our vessel 

2. Identify the cause – by switching or unplugging circuits

3. Eliminate the cause, stray current, using SeaBis.

FACT

The current that CAUSES marine corrosion can be very low – 0.00001 amp. 

So why use a multi meter?

Multimeter limitations:

A multi-meter measures current in series, is insensitive by at least a 1,000 times and has been lethal when used on amps. Multi-meters on amps have caused battery acid to ignite and explode resulting in a very painful death.

 

Incinerating!

A multi-meter incinerating while in my hands caused me to develop SeaBis.

 

SeaBis is safe and accurate:

We measure current in parallel with no effect on circuit being measured. So we are safe and accurate.

 

SeaBis System conquers electrolysis:

SeaBis Master System indicates the degree of aggressive and corrosive action of the stray current that causes corrosion so a decision as to urgency of repair can be made.

Explanation - the original cause of corrosion

The Cause:

The cause of corrosive current is the battery “0” volts terminal. In Kelvin Absolute Law terms (see Wikipedia) is actually at minus 12 volts for a 12 volt battery (24 for 24 volt battery). The metal contains electrons which are negatively charged. So the two negatives repel each other causing corrosion by dissolving your metal into particles. The Earth is at +1.2 volts so attracts those particles. So your metal corrodes to the Earth.

The Solution:

The solution is to use SeaBis Master System to eliminate the cause.

SeaBis explanation

How to stop stray current corrosion, explanation:

Assuming the lamp above your head is on. Now, leaving the switch on, using a rag, remove the lamp. The lamp goes out and current through the lamp is zero. So its element will no longer degrade. The element is your hull or engine.

Now there is no corrosion. The switch is still on so voltage has not changed. So there is no point in measuring voltage. SeaBis measures current with extreme accuracy.

Half cell meters, through hull meters, multi meters or probes measure voltage so cannot tell you the truth. The SeaBis Master System measures current!  That is why it eliminates corrosion.

 

Alternative to SeaBis System:

I have a laboratory instrument meter and current clamp combination that is accurate to SeaBis specifications. It cost me AUD2,600 at trade price.

Galvanic corrosion

When dissimilar metals approach, in a conductor such as water, current flows between them. That current is very minor compared to marine corrosion current.

That galvanic current is easily eliminated by anodes. However stray current corrosion must be eliminated first as it often is one million times more corrosive.

Testimonials

The SeaBis box proved very useful in tracking down multiple stray current problems aboard our boat. The leading cause was old household wire originally installed by Beneteau and new electronics that had not been earthed correctly. The service from SeaBis was excellent with prompt replies to my queries. I did really appreciate your help. Thanks again for your help, its been A1 service.

Marine electrolysis that causes marine corrosion eliminated

Hi Glen, Thanks for your help earlier today. I’ve easily isolated the offending components… spreader lights depth sounder …and the starter motor. I guess the latter is due to carbon build up as it is meant to be a separate earth unit. Anyhow, back on track now. Cheers, Mike

Marine electrolysis that causes marine corrosion eliminated

My wife and I are currently circumnavigating aboard our 45 ft. steel yacht. I purchased a SeaBis System after borrowing a friend’s SeaBis and discovering that I, too, had stray current – a flashing red critical light is hard to ignore. This was after the boat had been tested and cleared by the test bulb method. I have no electrical skills but, by following the system, I was able to detect and eliminate the four causes of stray current – a non-isolated genset, a VHF aerial not insulated from the mast, a fuel tank gauge not insulated from the SS day tank, and the connection between a non 12v computer and the SSB radio – to achieve a very satisfying green normal light.

Furthermore, the SeaBis has identified AC leakage from worn brushes in 12v fans and, most recently, a path between the brushes and case on my Balmar alternator, which blew the SeaBis fuse before causing any damage. I consider the SeaBis to be a vital element in diagnosing my yacht’s electrical health. I would also add that Glen has been a great guy to deal with, standing behind his product and providing a wealth of diagnostic advice.

You may use my testimonial with verification.

Marine electrolysis that causes marine corrosion eliminated

Six years ago I purchased a Dutch barge in Amsterdam, shipped it to the UK and spent four years restoring it to a fully functioning residential boat in my spare time. During this process I learnt much about the ways of vessels which has added to my automobile knowledge. One of the things I learnt was that corrosion was destroying my hull which lead into an investigation, this in turn lead me to the SeaBis. I completed How To Stop Corrosion and time has proven the cause is removed. No more stray current corrosion.

Marine electrolysis that causes marine corrosion eliminated

Well Glen your SeaBis system fixed the cause. No problems in 5 months. It was a deck generator and CB radio.

John Singleton

Marine electrolysis that causes marine corrosion eliminated

We purchased a steel cruiser 8 years ago and had problems not long after purchase with corrosion on the decks. When the boat was slipped we had evidence of metal corrosion which I think is caused by electrolysis, on the hull as well. When the boat was returned to the water I had a marine electrician check out the boat and he said that our boat was OK and the corrosion was caused by the boat next to us in the marina.

We then believed that was the cause, we tried to get the marina to do something about it but they did not want to know. When the boat was slipped 18 months later the corrosion was that bad we had to sand blast back to bare metal and repaint including the decks. We moved the boat out of marina and put it on a swing mooring, when the boat was slipped again it was evident again. I looked on the web and found the SeaBis site and purchased a unit since then the decks have stopped showing signs of accelerated corrosion. Although we have yet to slip the boat again to check the hull I am confident that the SeaBis unit is performing, as the decks are looking great.
