As im waiting for my sister to get to the house with the scanner i put the truck back to how it was when i got it for ****s and giggles. red/white to pos on back of alt. I started truck and was getting 26.7v across both batteries running. 14.3 on battery 1, 12.7 on battery 2. With key off...

Ok ill do this in a bit. What do i need to look for to make sure this is an isolated ground alternator? What do i need to do to make sure i have a 24v starter in it as well?

I went out and snapped more pictures and have more questions, i have a blue wire coming off of positive board that runs to a red 8 GA wire that goes no where. It came out of the wiring harness running down passener side out of a plastic holder that says 6 on it. Could this be an issue to my...

After seeing this im converting my truck to 12v tomorrow, ive had nothing but issues with this 24v system and i need this truck on the road.... Owned it a year now and only was able to drive it maybe 10 times because it is so unreliable.

Yes...i do believe its an isolated ground alt.

One was off that i overlooked and it was obvious:cookoo:.. the battery wire should be on the 3rd post on the POSITIVE BLOCK with the starter wire. Would that cause this issue? Also on my red/white on the pass alt, i put a plastic washer behind it. There was nothing on this little stud at all...

I did this, everything is correct.. this is why im so confused. Only thing i cant figure out is i have a wire(blue) coming off of the positive terminal board that connects to a heavy(8)red wire and this wire goes nowhere. I cant even find on any schematic what its there for.

ugh... Today i rewired the passenger side alternator. red/white to ground alt terminal(coming from driver side diamond post), red to positive alt terminal (coming from positive terminal bored), wired the orange fusible link wire to the red positive. As soon as you hook up the batteries, the...

AC delco thermostats that i get are made in USA, i work at the dealer (only reason i now)

So my batteries are correct then, just went and looked. Another thing i noticed is BAT 1 has 3 grounds for some reason, 1 going to the frame, 1 going to the valve cover, and then 1 going to the NEG TERM BOARD. Im going to have to address that also now. I got 2 fresh batteries, going to wire...

Could you probe the wire and check for power on both ends of the barrel connector?

Sorry took so long for pics, went away to hunting camp the past 4 days. Ok below i snapped a pic of the passenger alternator part number, the passenger side wiring post, and the driver side wiring post. If any more pictures are needed i can run out and take them. A confusing part on this truck...

Ill snap some more photos in the light, it seems though on the firewall my truck looks comparable to the other CUCVS on this site.. Ill get numbers and pics in the AM.

BACK OF ALT. Notice its missing the ground stud on bottom left corner for red/wht and i dont see where one could even go. Also notice where the red/wht goes, red wire is supposed to go there and im assuming its the wire down below here in the next attached pic. Wiring harness. The red wiring...

Ok so tonight after thanksgiving im going to go out and tackle this. I did a quick look at the back of my passenger alternator before work today and the orange fused link going to power was dangling behind the motor. The red/white was going to positive on back of alt(yikes). Only issue im...

I cant thank you enough for showing me that thread Doghead, im going to jump on all that tomorrow. PM me your address, im going to send you a m.o for a beer..

Hello, i was wondering if anybody can take a picture of the back of each alternator on their running M1008 and show exactly where all the wires go i.e to the blocks, grounds, etc and where they end up i.e firewall, frame ground, etc.. I cant get my printer to work to print the schematics and i...

Thats essentially what i wanted to do. I might just take a steel plate and make my own top part instead of buying.

Did you run the u bolts going straight up?

Was it hard to install? I ordered one Friday and should be here monday.
