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.
Corrosion CAUSE corrected, permanently
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 prevent marine stray current and complete correction of CAUSE.
Now switch off circuits until SeaBis indicates Normal (green). The cause was the last circuit switched off. It now has no power so is easily identified. Correct the CAUSE by following How To Prevent Corrosion. Support is included.
The faults are CAUSED by marine stray current corrosion and that is caused by fault/s on your vessel. SeaBis measures that stray current with extreme accuracy. To eliminate the cause switch off equipments until SeaBis indicates Normal. Now follow How To Prevent Corrosion, supplied with SeaBis Master System.
SeaBis is an easily installed 3 wire traffic light system, support included.
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 indicates that change of current. SeaBis is the only system to eliminate the CAUSE of corrosion, marine stray current, World-wide. Now prevent marine stray current with How To Prevent Corrosion using SeaBis indications to correct the CAUSE/s. Or contact us.
SeaBis Master includes How To Prevent Corrosion. It details process, typical causes and their repair. Free support value AU$80 or 1/2 hour online, is included.
In a hurry?Corrosion is generated by stray current caused by water in navigation lights, carbon build up, antenna, normal wear and new equipment. Keep SeaBis connected and you are warned so can prevent corrosion immediately.
Recreational and some commercial engines are used less than 200 hours per year. Prevent 97% of the CAUSE of corrosion by fitting a switch or solenoid. 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 our modified solenoid will prevent stray current – corrosion while engine is off. The engine is 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.
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.
We will support you. Contact us.
The original cause of corrosive current is the stray current created by moisture in navigation lights, carbon dust build up at motors or alternators, insulation failure, new equipment or bad design. The SeaBis Master System will identify and correct the cause. Using SeaBis will teach you how to correctly buy, install, maintain and operate equipment without creating stray current.
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).
AC – Mains / shore / inverter power. AC current (power) cannot cause electrolysis as it changes direction every half cycle / Hertz.
In explanation: If the cause takes off a metal particle in the first half cycle it will replace it when current reverses direction in the second half cycle.
Therefore AC cannot cause electrolysis – it is impossible.
DC (battery) current flows in the same direction, permanently.
So DC will continually dissolve your metal. 24 hours every day of the year.
Eliminate the CAUSE by using SeaBis Master and booklet supplied with SeaBis: How To Prevent Corrosion.
To prove there can not be DC in AC: 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 to flow current at an extremely large amount.
The reason we supply a 8 year money back guarantee is we are 100% correct. Stray current is eliminated, permanently.
That means no electrolysis, permanently.
SeaBis is an electronic device with How To Prevent Corrosion that WILL 100% and permanently prevent electrolysis.
Use the SeaBis System to identify then correct the CAUSE. So correct the stray current that is the CAUSE.
Permanently. No hull / metal penetration / additional coating or plating. The stray current SOURCE is eliminated.
SeaBis shows the invisible stray current that CAUSES electrolysis corrosion in real time.
There is no need to slip the vessel to see the anodes eaten away because SeaBis instantaneously shows a warning light.
When the SeaBis 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 prevent corrosion completes elimination of ALL CAUSES.
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, even other vessels are eliminated by SeaBis System.
Prevent electrolysis then rust and galvanic corrosion are easy to eliminate. Your metal, 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.
The technical reason:
To be realistic, measurements must be with everything at full power and at applied voltage (12 or 24 volts). There must be no limit in the measuring device and a current sensitivity of millionths of a amp. That device must have no effect on the circuit to be measured, whatsoever. SeaBis Master complies. Multi-meters measure at 1 millionth of an amp at 1 volt so have a error probability of greater than 1,000:1. In addition they alter the circuit under test. Therefore multi-meters do not comply.
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. reference or 1/2 cell measures voltage so both can only deceive you.
That is why I developed SeaBis. SeaBis measures current, accurately and safely. It separates the various types and levels of current. Therefore you know if your vessel is safe from electrolysis. SeaBis indicates the degree of risk so you can time your repair. Also if there is excessive AC in your DC that can damage your batteries or electronics. How To Prevent Corrosion completes the elimination of ALL causes. Permanently.

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 prevent corrosion completes elimination of ALL CAUSES.
DC (battery) current is the ONLY cause of electrolysis . The MAIN source of stray current that causes electrolysis is the vessels’ own battery bank. ALL CAUSES are eliminated by SeaBis System.
Prevent electrolysis then rust and galvanic corrosion are easy to eliminate. Your metal, paint, coatings and anodes will not be destroyed by electrolysis.
Your engine and hull will not be dissolved. 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.
There are 8,400 hours in a year so 200 hours divided 8,400 equals 2.38 percent of corrosion cause remaining.
To use methods of stray current elimination SeaBis MUST indicate NORMAL on all battery banks excluding engine. Then we can supply our 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.
Larger trucks, planes and some professional vessels are correctly insulated. That will be the result of SeaBis Master and How to Prevent Corrosion.

3. Eliminate the cause, stray current, using SeaBis.
The current that CAUSES marine corrosion can be very low – 0.00001 amp.
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.
A multi-meter incinerating while in my hands caused me to develop SeaBis.
We measure current in parallel with no effect on circuit being measured. So we are safe and accurate.
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.
The original cause of corrosive current is the stray current created by moisture in navigation lights, carbon dust build up at motors or alternators, insulation failure, new equipment or bad design. The SeaBis Master System will identify and correct the cause. Using SeaBis will teach you how to correctly buy, install, maintain and operate equipment without creating stray current.
The solution is to use SeaBis Master System to eliminate the cause.
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 or reference meters, through hull meters, multi meters or probes measure voltage so cannot tell you the truth.
Multi meters on current ranges actually measure voltage. The SeaBis Master System measures current! That is why SeaBis System eliminates corrosion.
I have a laboratory instrument meter and current clamp combination that is accurate to SeaBis specifications. It cost me AUD2,600 at trade price.
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.
We expect your SeaBis Master System, where it is permanently installed, will last for 20 years and will guarantee it, manufacturers faults only, for 8 years commencing on receipt full payment.

Should a manufacturing defect occur, we will, at our discretion, repair, replace, or refund the money paid to Podean Electronic Industries Pty. Ltd. trading as SeaBis for the SeaBis unit. Providing How To Prevent Corrosion has been complied with and we have authorized the claim and the return of the SeaBis System. Guarantee includes manufacturers fault/s only. Shipping is World-wide so is the responsibility of the Owner. Many have more than 8 years years in use so we require proof of purchase.
Do not ignore the AC Only light. When it flashes your equipment is at risk.
Comply with How To Prevent Corrosion. Then your warranty will be effective. We warranty SeaBis Master System with How To Prevent Corrosion will eliminate ALL CAUSES of corrosion caused by stray current – marine electrolysis.
1: ALL batteries and DC power, without SeaBis System, create the stray current that causes corrosion so permanently monitor them all. 10 cumulative days, without SeaBis, can allow corrosion you can, without your knowledge.
2: Batteries may be switched in parallel so one SeaBis monitors them all.
3: Time away from your vessel can be excluded as we will take steps to ensure there is no corrosion while you are absent – see How To Prevent Corrosion.
4: Equipment you cannot turn off is treated separately. Thus absolutely minimizing the risk. Contact us.
As always, we will support you.
Contact SeaBis and correct the CAUSE/s of corrosion.
It is much cheaper to identify then correct the CAUSE now, than wait until corrosion roughens so increases surface area and stray current increases. That stray current dissolves your metal to the Earth, increasing with increased surface area.
The SeaBis box proved very useful in tracking down multiple stray current problems aboard our boat. Old household wire was the leading cause. It was originally installed by Beneteau and new electronics that had not been earthed correctly. 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.

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

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.

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 Prevent Corrosion and time has proven the cause is removed. No more stray current corrosion.
Paul Michelmore
Well Glen your SeaBis system fixed the cause. No problems in 5 months. It was a deck generator and CB radio.

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.

Two Volvo engines with a carbon fibre mast and extensive advanced corrosion to engines. One has previously been replaced. The Owner and Peter traced the cause to a separate power supply in the instrumentation. Fitted an isolating diode and isolating switches to both engines. Problem fixed.
