Interior Lighting and Radio issue- Please help!
I canít find another thread that exactly matches the issue Iím having so Iím looking for some guidance.
Some back story:
A few months back, I bought a decent (or so I thought) 93 jeep yj as a side project Ö It took a few months of searching, but I finally found a rust free frame 93yj with a 4.0, new 2.5in lift and no other mods. I most likely overpaid for the thing, but it is what it is. Be ready for lots of questions. Iíve started to tear into the thing and noticed quite a few issues that I need to address, plus a lot of dirt under the dash...
So the first thing I wanted to do was replace the radio. The previous radio would not keep the presets if you turned the car off, so my thought was that the PO didnít wire it correctly. So I ripped the old radio out, wired up the new radio to the wiring harness and plugged it in. I couldnít get it to turn on.
So here goes my limited diagnosing skill. I checked my connections to the original radio harness, re-soldered and tried again. Nothing. So then my thought was that the radio was bad, so I wired directly to the battery and low and behold it turned on with the red aux from the original harness and the yellow power from the radio connected directly to the battery. So itís the yellow circuit the radios plugged into which is the issue.
When I bought the jeep, the interior lights would only come on if the key was either in the aux position, or turned on. I checked the wiring and you know what I noticed; the same yellow circuit that was giving my radio trouble connected to the interior lighting. So I cracked open a repair manual I found online (thanks Redneck Garage) and looked at the interior lighting wiring diagram. Not sure what Iím looking at or even where I should start checking with the volt meter.
I checked my fuses and they were all good. My door grounds are all fine and the bulbs are good as well. If I connect everything in the below sequence, I can tell that the dimmer switch is working. Everything else in the jeep is working. I also checked the interior fuse panel for fuses 7 and 10 and both have 11.8v coming from the block. I did notice that there was an orange and white wire hanging down, but I think that it has to do with the radio illumination so Iím not too worried about that (if not please warn me now).
I can get both the radio working, as well as the interior lighting if I connect both the jeep radio yellow circuit from the jeep radio harness + yellow wire from the radio + a wire directly to the battery positive terminal.
Any ideas on where to begin? Where would the power enter the circuit? Any and all info would be greatly appreciated!
