Masse - and Masse + lights
Dear Amel Group Friends
I’m asking you guys if someone had the same or similar experience and what is your advice for my question:
I have a Negative Leak light on the 24V Pump-Motor of the Dessalator Duo. There is a Bonding wire (yellow/green) that runs from the Bonding strap in the grey-water sink to the Dessalator. But this wire is disconnected on the Dessalator unit. When I’m connecting the 24v pump directly to the bonding system the negative leak remains. Light is still on.
The light does only switching OFF when I’m switching the pump on, or if I’m disconnecting the negative wire.
BTW: I cannot see any corrosion on the Dessalator unit. The DC motor itself has no contact to saltwater, - it's only the pressure pump in contact with saltwater (but no 24V connection).
- Does it mean I need a new 24V DC Motor?
- Are there any longterm experiences what can happen if a negative (or positive) light is not fixed?
- What is the affect and result of a longterm neg. vs pos. leak?
It’s very easy to get miliAmps of current on a 24V motor with brushes and wires, etc. Are we AMELies to paranoid with these lights?
P.S. I still not fully understand how these lights working. To my understanding it is indication a leak from Masse - and Masse + against the AMEL bonding system. Maybe I’m wrong?

In the circumstance you describe, the light indicates that there is a connection (resistance) between either the positive or negative and the case of the macerator pump. That "connection" is usually saltwater leaking past the seal on the pump. It is an "early warning system" that your seal is leaking and your pump will fail. A switch such as you suggest will certainly be a "see no evil" solution.🙈😀 You could accomplish the same by disconnection the yellow/green wire from the case, but, don't you really want to know when you have a seal leak.
