I have a Catalina 400. A Blue sea battery combiner charges my house bank and starter battery off of the alternator from Yanmar diesel engine. After about 2 days of cruising the starter battery continues to charge while motoring but the house bank does not. I have checked the fuses on the combiner and those seem to be fine. Has anyone else had such problems?

Is your charger attached to your house or start battery?

Does the combiner show it's combined? Green light on?

Check the combiner ground.

Blitz called all the regular things to check. As he alludes too, your alt wire should go to your biggest bank (house). Hard for it not to charge then (unless its got a bad cell(s))
