Re: [Amel Yacht Owners] Masse - and Masse + lights


It would work...If you are going to go to the trouble of installing a switch, install a double pole switch and turn off both positive and negative. As you know there is better than a 95% chance the offending item is one of the macerator pumps. I am guessing that you might get a 2-6 months more  life.

I have been diligently checking the Masse- and + lights in the companionway. Over the past 5 years when one of the lights go on (usually the Masse - ) I go and disconnect the power lines to the forward or aft head and sure enough, the leak of current to ground stops and I replace that Jabsco pump. Recently the Masse light did not go out until I had unplugged both the heads at the same time, indicating to me that both the head pumps were leaking to ground.

It occurs to me that instead of replacing the pump, I could just install a toggle switch to the offending brown or blue wire, so that I can turn the circuit on when anyone uses the head, and turn it off in th interim. Then I could continue to use the offending pump until it does a natural death.

Am I fooling myself or would installing that switch stop the current leakage to the Amel bonding system?
