Blackout lighting switch?

That's where my lighting issues were coming from.
Missing a jumper wire in the dangling blackout connectors.
PO(?) removed the B/O switches.

30 amp fuse is loose in the fuse box. Common problem. Cleanup connections at fuse. I have removed the fuse block and cleaned it up and have had success. Some beyond that and need an in line fuse put in place. Actually 2 inline fuses are served from that leg in the fuse box. Good Luck. Sounds minor. common problem. Lots of help available.

In my early days with CUCVs (which always seem to have electrical gremlins), I tended to start with the complex answers to questions, like swapping blackout light switches, etc.
Then I figured out the fuse box was the source of many of my problems, the most common being corroded or just plain loose fuse holders. One explanation for this might be someone adding an additional power tap at some point by shoving a spade connector in next to the fuse.
Check/clean all of those connectors, and pinch them a little closer together. Best to go ahead and replace old fuses with new ones (they're inexpensive!).

Once you've done that, if your problems persist, start the more complex troubleshooting.

Cheers

Definitely also look at whatever else was added to the factory wiring.
Who knows what else you’ll find to fix.

Yes that was the prob 30 am fuse, not blown but has been loose and hot. Replaced all fuses.

Also always use quality fuses. The cheap made in China versions they sell at Harbor Freight can cause issues.

Many of the common repair tips can be found in the Helpful Threads sticky at the top of the CUCV forum

Excellent advice.


marbaja252:

1. Don't add anything to that fuse box. It's already badly under-designed.
2. If someone else did, re-do it so that it's not putting a load on that fuse box. Figure out what was added, and how, and start a new thread. Some of us will walk you through removing the butchery and then doing it right.
3. Read the stickies.
4. Please STOP SHOUTING. It's rude to type in ALL CAPS.

My understanding on those was that they often failed to burn out when the designated amperage was exceeded, so something further down the electrical line had to instead. That kinda negates the purpose of a fuse!

a 50 dollar switch will burn up to save a 10 cent fuse IMHO
