Today I've been in the boat measuring. Below you see the windlass and control box
And this is a close shot of the control box
And this is the wiring
diagram from lofrans
When the engine
is shut off I got 13 v between M1 and +, M2 and +, B2 and +, B3 and +. When running the windlass the voltage varies in B2 or B3.
on I have 14 v between M1 and +, M2 and + but 0 V between B2/B3 and +.
So I have current as far as to the control box
but not to B2/B3.
I suspect that the feed cable that goes to C is the problem. It might be connected to a breaker that are controlled by the alternator
current. I can't find such a thing though. Below is the alternator
And the battery
