Ok guys,
I checked everything out and there wasn't any light or switch left on. Only 3 days had passed since we had returned. When I pulled the old battery out, it had a puncture, how deep I don't know right through the C in Centennial but it was still full and didn't leak.
Secondly Rog, you are speaking Greek to me. There is no battery cut off switch now, and for mine please just tell me what model to get based on my coach and truck named below.
Third, Jim, I am glad it was a gift but even if there was a light left on which I dispute, 3 days is a real short time to deaden the battery. Is it possible I just had a defective battery as my repair shop said?
When I put the new one in tomorrow, I will check the whole coach from top to bottom, easy with the corrugated underbelly sagging so low, to make sure all electrical systems are off, including the UDC. If I wanted to add 2 6 volt batteries, couldn't i place them in the front storage dept next to the gen prep? I have to figure out some sort of system to use my sleep apnea machine which eats up 9 amps an hour if I want to dry camp,once i get a genny.
