I have started our boat many times while still attached to shore power without any incidents. But I have always shut down the shore power/charger almost immediately thereafter. So I can't say whether I would have a problem or not if I left it connected during prolonged periods of engine operation. Edit: We are running a Xantrex TrueCharge20 charger.
It would be interesting to know more about the wiring details.
