Thanks for the quick reply. None of my friends, (both of them) are electrically inclined.
I am in Pgh. PA. Are you in the neighborhood?
My former Roadtrek had a 12 volt line running form the house battery up to the chevy battery and the whole system was tied together.
Under the hood of my current Ford chassis, do you know if there is a 12 volt line coming from the house battery?
I could always hook up a "Battery Tender" to the Ford battery using 110 volts from my Home outside outlet.
Maybe I need to find the BIRD if I can find it.
Thanks for all your suggestions.
