24volt circuit in CUCV fuse block

Some one posted this a while ago but I lost the link to the poster.

Default CUCV Fuse Box Layout

There are some errors in the TM diagram for the CUCV fusebox.

I will attempt to point them out as I find them


Here is a "clean" fuse box with all the proper fuses and labels


ITEM

3 - not used except for the M1010. The M1010 uses it for Ambulance Accessories

This is in response to woody127s statement below.

Firefox:
don't think so since according to manual, the fuse box(under dash) is 12 volt only. Again the radio will come on, but no sound. It finds the strong radio signals, so I'm not sure why.

Warthog posted the info. The picture of the fuse box is from my M1009.

Fuse #12 is 24 volts and is labeled so on the fuse box.

It sounds as if the radio in question, lost its audio output amp. The RF portion seems to be functioning based on the signal strength indication.
But I am not a car stereo expert by any means.

Thanks for posting this, my M1009 has no lights whatsoever. My Fuse box is partially melted, and I'm looking to rewire the whole thing.

Your best bet may be a wire harness transplant from a junked or parted out CUCV, 1009, 1008 and 1028 have essentially the same harness. It is not difficult, much easier than making custom harness.

Thx Dependable, I'll start my search

Let me know if I can be of assistance in your search. I have a few donor vehicles. They will need removed from the vehicle. Engine harness and under dash harness.
