1986 CJ7 Gauges PROBLEM!!!!

Hello
its been a while since i have been on. Here is the problem.

Problem:

Ammeter gauge, Temperature gauge, and oil pressure gauge, Fuel aren't working. they were working a few days ago.

Hypothesis:
Bad fuse or bad ground. But wait, if its a bad ground, the lights for the speedometer shouldn't work correct? What fuse supplies power to the gauges? Pictures of the fuse diagram would be helpful. ALso if one has a key for the fuse block, can you please post it.

Solution:
n/a

Thanks again for your time and input!
Thanks
Lance

This is the 1984-86 fuse block layout. Looks like the 15 Amp fuse to the computer and "instrument cluster" i.e. gauges. (LPS). I do not have a pictre of the real life fuse box but you get the drift.

If your engine is working have you got the computer? If so how is it being powered?

It may not be the fuse of course.

Enjoy frustration? Then look at the electrics.

79 was almost the same as the 84 fuse box posted above.
Some of the fuses sizes are different to support the computer load.

This is an 82 fuse box but should be the same.

Get your test light out and start checking. IGN LPS

What kind of connector is that in the radio. In my new-to-me 84 CJ7, the PO has rigged an awful tap for the radio and the factory radio slot is empty. It would be nice to wire it like this one.

I also have the gauge outage in mine so thanks for posting. Any other advice would be helpful.

Many thanks!

That radio plug is just a spade connector in a housing.
