Just one general caution. It is not a good practice to use the alternator to charge heavily depleted house batteries. It is really tough on the alternator.
Yeah, I know, then why are most motorhomes wired to do it that way. It certainly keeps the 12V house systems going while underway, but you really can put a strain on the alternator with house batteries that are way down. The problem is the heat generated by making all that current just causes the alternator to prematurely fail.
This doesn't apply to the rigs with the huge 50DN alternator that is oil cooled.
