Even with the overwhelming jeep following on the net, I cannot find any bootleg FSM's online either. What gives?

We have one that suddenly developed electrical issues...something is backfeeding juice into the main ignition circuit, meaning that it's impossible to turn the engine off even with the key out. Even if you pull a fuse to kill the engine, some of the other accessories remain powered with the key off including interior lights, gauges, dash warning lights, etc. I can't trace the problem because I can't find a good enough wiring diagram...and the f*(&^%^g fuse box isn't even friggen LABELED.

I have your issue into a Jeep Guru. Hope he has an answer for ya.

Wish I could help Kevin, I have a '98 FSM which does no good for '93 model. I will say it sounds like the main ignition relay is doing some naughty things, internally shorted. Lemme see if I have the old Haynes manual for my old '88 kicking around somewhere. They should be similar, at least it could tell you which fuse is what. If memory serves though, the fuse/relay locations and functions are in the owners manual

You have a bad ground somewhere. "Do the dome lights stay on and the ignition circuit won't shut down? Does it ever shut down? I'd go to the dealership and photocopy the pages that show the ground locations. Then I'd go check each one.
The factory manual has a section with each ground desgnation (i.e. G206) and tells what components ground through that connection. Then another section will show you a pic of G206 to help you phisically look at that connection.

LMAO!
It's very intriguing how fast a thread or topic can change.

BACK ON TOPIC!
Let's limit XJ work to PM's.

It's a decent way to find the relay, but not so good for tracing all the wires back and forth to find the short if one exists. If a burning smell was present, likely something rubbed through and or melted.

I don't either unless the relay was gnd triggered which is rare in american cars. Usually a bad gnd causes circuits to stop functioning, not keep functioning.

It could be as simple as the ign switch itself went bad, or one of the wires leading away from it went to shit. There's alot of movement around the colomn and the earlier ones are known for getting loose. As in the wheel moves up and down becuase the column nuts became loose. That could easily short something out.
