Gerald, others,
Apologize for slow response, busy getting settled back in.
Out of curiosity I disconnected from shore power and waited about 15 minutes. Then checked battery and from the Aladdin the readings are:
Chassis batteries were at 12.6 with ignition on.
House batteries were at 12.9 but had a 6amp discharge even though nothing, I believe was left on.
Hooked back to shore and then house batteries showed pretty big charge of over 30amp and reading of 13.4v. This, again was after maybe 20 minutes. I think they need to be checked as well.
All readings off of Aladdin, so probably not totally accurate.
Has been nice here but cooling off below freezing over night in the next couple of days, so I’ll be putting it in the heated shed. Can work on it then. I may put a charger on the chassis batteries.
To remove and clean or replace the BigBoy, obviously disconnect and no genset, and do I disconnect battery switches?
Just for interest, if the BigBoy has failed or failing I assume it happened on the trip home as the coach was sitting for 3 months in Texas and fired right up a few days before we left, albeit with the usual initial slow crank, then faster and start.
Thanks as always,
Jeff
