Power problem, Battery? PO said it was new.

Thanks for all the good advise! I left the van on sure power last night and it didn't charge the battery. I believe I have a isolator and it looks a bit rusty on top. I'll clean that up and then I will have to drop the house battery to check the terminals for corrosion. Better off doing all that here in Tucson then in the frozen NW!!
Thanks.
