Richard is correct. If your house batteries are not charging off of the engine alternator, the merge solenoid (as opposed to the start solenoid) should be checked and likely replaced. It requires a continuous duty solenoid, not a starter solenoid. Putting a starter solenoid in will give great results for a few minutes before it self destructs. Yes, I have personal knowledge of this.
