ALL Bat positive indications – contact us immediately. Especially if you have both 12 and 24 volts. Fire risk can be eliminated.

SeaBis Master LED’s explanation:

In addition, your work is reduced by half:  SeaBis indicates battery side with fault.  “Bat positive” or “Bat negative”.

1:  Normal (green) = there is no corrosive current
2:  Caution (amber) = very low current, very slight risk
3:  Serious  (red) = visible corrosion in 6 months
4: Critical (flashing red) = visible corrosion in 3 months
5:  AC Only (flashing red) = your batteries, electronics and yourself are at risk.  Excessive AC (110/240) on top of DC (battery). Common cause is power supply Active, Neutral or Earth reversed so your life is at risk.

Marine electrolysis CAUSE prevention procedure:

Install SeaBis Master:

Connect to battery power:

1:  Brown to battery positive

2:  Blue to battery negative

3:  Green / yellow to metal hull or metal engine body

4:  After that, observe SeaBis indicators:

For instance, if you see other than either Normal (green) then marine corrosion is ongoing.  In addition, SeaBis Master indicates the side of the battery causing stray current. Therefore, halving your work. According to Bat + or Bat – indicator: Switch off or disconnect circuits on battery positive OR negative until you have a Normal.  Above all, when either Normal is On there is no stray current

5:  In conclusion, the last circuit you switched off was a cause of marine corrosion

Consequentially, leave it switched off

6:  After that, to determine if there are any other causes, touch connect the remainder, one at a time

7:  Any that cause other than Normal, leave OFF. Reconnect all that indicate Normal

8:  In conclusion, you will have one or more circuits off / disconnected.  After that, see what has no power, and you will know the cause/s.
