First - apologies. I posted this on the mobo forum but it seems devoid of techies so it's duplicated here...
was on a pals boat last week, and the domestic pressure pump kept tripping the overcurrent relay. It's on a board of four units, each with reset/set wires to the dashboard switches, some circuitry, and an indicator LED.
There is a choice of shunts - 10 amp, 15amp and two positions per circuit (giving 10 - 30amp capability)
We had to swap the pump cable to the shower drain circuit, in order to keep things going.
Does anyone have the circuit diagram for the current-sense components, or any further information to help us isolate/repair the problem?
(we can't easily get the board out to see the printed circuit)
Thanks in anticipation,
