Lost all 12V power in my M1009

[jlhobdey]

Hello,

I just bought a 1984 M1009. The alternator went out and caused me to not be able to start her, I jump started her and now none of the 12V devices are working. All of the lights including driving, brake, dash, etc do not work.

Anyone know where and what the device is that could have gotten blown?

Thanks

well there are Two alternators in your cucv.... and you do have the black out lights switches in the correct positions?

Yeah, I just replaced the driver side alternator, and the passenger one was already showing good output. I tried the blackout lights in every postion and it didn't help at all.

Fusable link blown perhaps. . . .

Yep, check the fusable link that feeds the 12v system.

It is the smaller red wire on the negative terminal of the rear battyer. It changes to a blue fusable link at the 12v ENG WRG HARNESS BLOCK. It is a 12ga link.

It is located on the firewall next to the brake master cylinder.

Download the free repair manuals and study the wiring diagrams that are in the appendix of the -20 or -34 manual.. Also study the first few pages of the Troubleshooting Section.

Also spend time removing and cleaning all the fuses and holders in the fusebox. Disconnect the batteies first. The fuse box diagram is in the manuals.

Spend time reading the CUCV Wiki and the CUCV stickies.
