Help - bowthruster breaker won't latch

[boatingdave]

The problem here is not with the thruster contactor, its with the remote battery isolator switch, this is totally seperate to the thruster and only isolates the power to the thruster, it has nothing to do with motor direction control.

Ah, Ok. Now read the thread on the iPad instead of the iPhone and have read it through. Sorry. . Similar principle just different part of the circuit? It could still be burnt contacts?
