So that was a burnt fuse.
I am now getting 12v from the house bank, tapped into the selector switch at the bow to power the dc to dc chargers. When I turned on the house bank after replacing the
fuses the two came on and started sucking 40a from the house bank.
But even if my house
batteries are not being charged, they are still powering the dc converter chargers in the bow. So there doesn’t seem to be a combiner switch in place to only power the forward dc to dc converters when the voltage from the
batteries is above 13 (or whatever the combiner is set at).
I feel like
Jeanneau would not make this a factory set up as your house batteries could quickly be depleted with bow thrusters or maybe if everything is fully charged it won’t matter?
Why would this make sense as a setup?
