I had some time to work on it today. Both new batteries won't take a charge. I put a set in out of my 1ton . it starts and runs. I'm not getting any charge from the alternator. There is a 8 amp draw off the batteries which I think is a bit much considering nothing running. I'll have to chase...

Yes it’s a part time 12/24v system unlike anything I’ve worked on before. It seems the right battery is the one that is usually dead. Was wondering about typical problems and short circuits that would cause this

Batteries were dead at the dealer and about 5 years old so I started by grabbing a new pair, cleaned all the terminals then drove it home. I'm going to borrow a DC clamp amp meter to check out parasitic drain. I don't know much about this 24V system does anyone have a starting system schematic...

Having problems with our 1993 fj80 24v diesel. Batteries go dead after 3 days sitting.The other day I boosted it to start it, it won't shut down now and all interior electronics are dead. with engine running batteries show 6V and I have to pull wire off battery to get it to shut down. Any Ideas?
