Batteries,electrixal issues just help
I have a 2002 Thomas chevy 3500 express,battery drain, first bus so had no idea it has another battery. So whete is it located?0 I'm sure that battry is draining my new battery, so can I disconnect and only use one bsttery? How many of the 200 pounds of wire can I cut out? The panel above the drivers has a seleinoid looking thing with a fuse box of emergency lights things like that. Do I need them? Any help appreciated. I have my headlights,binkers,tail and brake lights all on switches,soooo??? Any help here with this nitemare of wires and location and possibly ditching the other battery when I locate ut! Thanks!
