Dash Knob indicator light wiring help

Any good write-ups on dash knob indicator light wiring? I put all new indicator lights in my 81 cj5 a while back, plugged in a bunch of orange and black wires. I have seen where they possible piggy back off one another so the order must be correct, also have seen alot of info on gauge lighting, just not any on the knob indicator lights. Right now my 4wd gauge light works, brake light is constant on. the courtesy dome lights did work until I tried to make progress last night. gas gauge, oil pressure, voltage speedo, odo all work. new headlight switch, hi beams and low beams work. I know the knob can be turned to brighten and dim lights. it does nothing for me though. Do the knob lights run off the Ign. lamps fuse along with the gauge lights?

It might be your headlight switch not working correctly. I know that before I pulled my wires out, I would have to twist and hold the knob to get any dash lights. It's on the list for replacement. For the break light, look at the switch and make sure your ground is good. I had that problem with mine.

My switch is brand new so I am sure its not that. Im not getting any power to the orange or black wires that plug into the knob lights. I do know that as of right now.

I have a painless wiring harness and I have a fuse in the box and a relay for the headlight switch with an inline fuse. Check all your fuses. If not, trace back to find out where those wires have power with your volt light

There were two switches for the CJ.

Make sure it's identical. Some have a jumper. Some don't.

Good one!!

I'm having the same issue myself, Smitty. Cluster has lights, but dash indicators do not. I apparently bumped/pulled something loose during my dash repaint. I'll keep my eye on your thread to see what you come up with.

Well that should help out some. While doing other work on the jeep today I finally found my dash ground hookup location. I am going to try and start there tomorrow. Thanks for the help as always

John, what do you mean some have a jumper, how would one identify this jumper you speak of? Also you said make sure its identical. Identical to what? my previous light switch?

just a follow up. My jeep battery was dying last week. Pretty sure it was John Strenk who had a post that gave me the directions on using the negative battery terminal, hookup, and test light to find out if my jeep was pulling amps while off. I discovered my horn relay was drawing power so I pulled it. Also pulled a lot of other fuses trying to find that out. I did find a dead fuse that I replaced, pretty sure it was the acc. fuse. It was a 20. Went to check the jeep last night after being gone all weekend and the power was fine so pulling the horn relay worked. AND I now have dash lights! I know I have checked my fuses before, first place I would ever check for any electrical. Had to of been what it was though. Either way it works now. now if I could just figure out my brake problems I could go for a night time ride.

There is probably a short in your steering column that kept the horn relay activated.

Pretty soon you will have to hunt that one down also. But that's pretty common.

Well I took my steering wheel cap off and there is definitely something going on up there. I dont know the correct terms for the horn hookup parts though. Basically a goldish disk with 3 bolts and a black wire under it surrounding a spring. That disk makes all sorts of small sparks at the slightest touch. The PO put the new steering wheel on so i am sure he did something wrong, said the horn used to just go off so they eventually unhooked it at the horn. sorry for my ignorance on the parts, haven't gotten to that yet in my jeep training.

sounds like you have an aftermarket wheel. Snap a picture and we'll look at it.
