It should be negative ground. Unless someone went to the work of changing it for some wierd reason.

Every deuce I ever worked on or had was NEGATIVE GROUND. The only positive ground trucks I had were old school Mack, Brockway, trucks and early Diamond T . And they were all civilian trucks.

I had a Freightliner once that was positive ground.....a frigging beotch to put a CB radio in.
Sounds like he was the "shade tree mechanic" from ell.
I would address that situation immediatly.

You got a picture? Are you referring the fact that the batteries run in series and one of the negative cables from one battery goes to the positive terminal of the second battery? Or are you referring to the fact that the positive cable (red) that goes to the starter etc. is benig used as the ground and they are using the negative (black) cable that normally bolts to the frame as the positive?

What year is it I bid on a studebaker at fort McCoy a couple years ago that was positive ground . They blew the batteries slaving off it.
Same area. Very possible

This could turn out to be a shocking thread

Seriously though negative to ground, batteries are in series, and your alternator should be adjusted so the needle is on the white mark in the green area.

Frame --> Batt 1 NEG
Batt 1 POS --> Batt 2 NEG
Batt 2 POS --> All other electrical system

yup FuzzyToasters truck drove it home last weekend. about 100 mi made it half way then clutch went to slipping up hills. Tranny front seal i guess went to leaking. some 90w on back axels and 90w on the bellhouseing hole on the bottom of the bellhouseing. Have not had time to check out yet. So far pretty good truck working on charging sys now.

Drain 12oz out of the trans, remove the clutch inspection plate, and spray some brake cleaner up there. Should be good to go.

Gee, wonder why the alternators didn't work. And yes to it being a negative ground system. I believe the starter does not care which way it gets voltage, or the lighting for that matter.
Bet if you hook the batteries up negative ground, and repair the wiring, a good alternator will charge.
