yes im doing it right nowI have a 97 PU 5.7 in a GMC.
Its setup with a isolator but when bought only had the one battery. When I bought the truck in 2012 it had this setup. I tested it and it works, but I do not have the extra battery in it.
I have two HD RV deepcells. Question can I use a deep cell as a the alternate battery off the isolator?
The truck is power nothing, Just PS/PB nothing else like windows, door locks. Its the 5thwheel puller.
Specs 100amp alternator and isolator.
I thought about a bigger alt, but then would need to upgrade the main alt to #4 wire, and the extra battery wires as they are not set to handle anything over maybe 125amp, plus replace the isolator with a heavier one. Trying to see if I ca get by with stock on hand so to speak.
Thanks
