I've literally looked for 2hrs. For 1991. Can't find any confirmed wiring. Please enlighten me with information please

And I swore I've seen it all..... yet you add even another thing to the list! I've never seen an idle up switch! I'd love to have that. .... ugh now to scour the inter webs on doing it to a 1991

In your instance is it possible to transplant the whole assembly locker and all into the MJ?

i have low pinions in both my MJ and TJ never had a problem. for what its worth...

should be plug and play! or in this case cable and play... I did the exact opposite, I used a renix mechanical tcase on my electric speedo and it works flawlessly

ignition switch and new (used) marine battery in! good to go, now getting the old Meyers rebuilt and ready for winter!

I'd sure like to see a pic of it. They are not shown as an option in the parts manual anywhere that I can find. :hmm: I agree!

yep I guess it was just the batteries.... as its been good since the third battery. thanks for everybody's input!.

Does that center console have a shifter block off plate?

that's a sick truck! very nice! I had a '91 blazer 2 door 4.3 4x4 as my first vehicle. I loved the crap out of that truck. sadly I got hit head on and totaled it.

So left the fuse in last night. And come 7pm tonight when I went to turn it on. BAM 12v and formed right up. Even with the dome circuit powered.... I'm going to monitor it still the next couple of days. But I guess its possible I had two failing batteries...? The original one was a very old and undersized battery. So honestly not surprising. The next was only 3/4yrs old originally from my TJ but in my s10 for the last 2 years and fully reliable the whole time in that (but also a standard 4banger). But this marine battery I inherited seems to be doing better. Also talked to dual electronics and they said its suppose to glow red. So should be OK I guess

also, on a side discovery. my drivers door switch for the dome lights never worked. in searching for this problem i found that the wires on the back of the switch have fallen off into that body cavity.... is there any easy way to retrieve these wires?

well with the dome fuse out all night i stayed well above 12v on my battery! and fired right up, so it's definitely in that circuit. I'm thinking it has to do with the radio. its a "dual" head unit. I'm going to call their customer support tomorrow and question them on that backlight staying on and if its supposed to be there or not.

not to hijack this, but i see you have a typhoon, could you post a picture of it? i LOVE those trucks

Yes My 1991. I checked radio wiring again today. If I recall correctly the radio side has yellow wire constant(memory) and red wire switched (power). Which I had/have going. Yellow-pink red-purple. So that should be correct.

Just found a semi-decent fuse chart. So the dome fuse holds the memory power (constant?) and radio fuse is the ignition power (switched?). Correct me if this sounds wrong. http://jeep.zerok.ru/index.php?page=105&word=dome+light

I'm just kinda puzzled on the power wiring. Why have independent clock/radio fuses if they are all controlled by the dome fuse. Also possible culprit (but sceptical as problem didn't start at the installation) there's a faint red light behind my radio dial (not whole thing) that stays on all the time. Now when I pull the radio fuse this stays lit. But when I pull dome light this red light turns off.... no idea why or how.

That's one of my next tests. I'm waiting tonight to see what happens with the whole dome light circuit unplugged. If I have juice tomorrow I know ive found it. And then I'm going to single out each thing from there.

I pulled the dome fuse just to double confirm my meter reading and diagnosis. But I also swapped my battery for a marine deep cycle. So we will see if that helps.

I tried leaving the glove box light out. Didn't help (I changed all interior bulbs to LED anyways). Cargo light is not factory. (On its own circuit) So I know that's not it. No floor lights on this model. And both b pillar lights are unplugged.

Radio is a used unit. Installed about two months ago. This problem is only 2/3weeks old tho.

OK so I did some investigation. Put my meter in series with the positive battery cable on 10a. And I was pulling about .23a. As soon as I unplugged the fuse panel maxi fuse it dropped to 0a. So I went off to the fuse box. Unplugged everything and started replacong fuses till the amp draw returned. Found to be accociated with the "dome light" circuit. As soon as that was added/removed I gained/lost the .23a. So I tried unplugging both done lights. Didn't help. Tried unplugging both door switches. Didn't help. Also found that the dome light fuse controls power to the clock and radio.... but both clock and radio have their own fuse. But can't understand why? Radio fuse and clock fuse both disable just themselves. But dome fuse cuts all three (dome, clock and radio) how or why is this? I don't understand it

I don't have a pic of mine currently. But I was able to use the factory striker hole for the lower bolt and then just drilled an upper hole for the top bolt. Then just popped b pillar plastics off. Stuck my hand up the column and put big washers and nuts on.

1991 Comanche (obviously). HO-4.0/AW4 Started happening about 2-3 weeks ago now. Battery will die over night/ extended periods ~6-12hrs. Is there any common power drains associated with these trucks? I've swapped batteries with another truck I have. And problem stayed with the Comanche. So its not the battery. I also tried replacing my ignition switch (not tumbler) as that was also a known issue for other problems I was having (won't run starter, radio losing memory, ect). And that seemed to fix it (day or two of starting ok in the morning) but problem returned and battery was under 9v and wouldn't start again. I plan on getting a DC amp clamp this weekend to measure my positive lead and try and fuse out legs to track it down. But just curious if there is common draw components.

Looks good!
