Smaller the number, the bigger the wire. Bigger is better in this instance.

Does the fan power go through the switch, or a relay? I see in post #1, the switch gets hot with the fan on....is it "hot wired?"

Here, with a bit of hassle is a diagram for 93....(u gotte go IN there)..http://www.jeep4x4center.com/knowledge-base/index.htm

12-2 is solid core copper for homes. Because flexing can easily brake solid copper that is bent allot, stranded copper is used in autos. 4 gauge would work, but IS also OK for a 6 volt starter. Just for now, run whatever you can find from a good body ground to a solid place on the engine. 6 gauge should handle anything but the starter. (and it will actually handle that). But whatever you have, the romex, a cord from somewhere....

Sheez! Sorry that just broke out! You gotta ground the engine to the uni-body!

i don't believe its hot wired. it should be all factory. i think i'm confusing what youre asking. what know is that the fan speed control switch (5 Prong) has gotten really hot and melted the connector attached to it. however all 5 speeds still work. so is it something in between the ignition switch and the speed control making them both hot?

as of now i cleaned all the grounds the one to the right of the dip stick the two below the a/c compressor the battery ground and the one to the right of the air box.
and i put the strap on the the original stud in the back and the other side on the stud to the right of my new finger decapitation hole.

one of the two in a vertical arrangement hope that works temporarily. is it an important ground? i see it called the radio noise suppression ground is that all it does?

I'm concerned about that toasted looking wire in the photo. How well does it's female spade connector fit on the ignition switch? Did you clean the female spade? Take it out of the plastic connector and squeeze it so it fits tightly?

I'd wonder if the connections there are not still an issue. I don't know. The recipitacal deal that grabs...if it/they got really hot the metal might "loose temper". Get a little soft. Sucky when a bad connection makes it get hot which can make it connect worse.

Hopefully somebody here has an answer. It's not imposable to use a tiny shim or dental tool to slip in from the front, flat side of the female connector and depress the little spring catch that keeps it plugged in to the connector.

With it out it could be wire brushed, inspected, tightened a bit with pliers...Idk! A bad connection surely will get hot if it needs to pass much current.

Don is 100% correct in his description and assessment here, even if he can't spell receptacle. Do what he says before proceeding down any more rabbit trails.

ill check it out better tomorrow. i do remember cleaning it really well back when i had cps problems and we thought maybe it was the cause ( before i got on here and learned a lot ) it does plug in there pretty good with a good snap/click despite the side connectors being broken.

Yea, with cruisers (2nd), and another look at your pic...I bet that's it. Besides the blade connector, it's crimp on that wire can be a suspect as well, especially now, since it's been baking hot.

I'm glad you felt like typing all that out. You should copy and save that. No fooling.
