Re: Battery Charging Problems

Your alternator is working with an output of 13.7 volts. The engine battery is good.
The house batteries loose their charge when engine runs.
Skip the study on amperage draw, and retrace each cable.
Try this:
With engine battery charged, shore charger disconnected, and engine running, do the house batteries take a charge? (13.7v or so).
Or this:
The shore charger is suspect. Monday my friend called me over to look at his dysfunctional charging system. Turned out his shore charger had one fuse blown at a house terminal. My Volvo donated a 30 amp fuse to replace the blown 40 amp , and all worked thereafter!
