We pulled over, he popped the hood, reached for the radiator cap and burned his hand. SO HE GETS A TOWEL AND OPENS THE CAP!!! Luckily he jumped back and somehow didn't burn himself bad. I'm a ***hole, so of coarse, I laughed my butt off.
back in highschool we ran into a situation where we had to open the radcap while things were running and what we ended up doing was grabbing some coveralls and engulfing the entire cap with them so any spray was right into the fabric and not on us when we opened it

I actually did this somewhat when I flushed my coolant. That's why I added the last part. I let the engine cool for about 15 minutes while playing fetch with my dog. I took off that plug on the bottom of the radiator thinking that was a long enough wait. Wrong. As soon as I turned it 90 degrees the plug flew off and coolant sprayed out like a jet stream. Luckily I was laying to the side and using channel locks to take it off.

Thank you sir. It was worth the few hours of writing. These ZJ's can be a pain sometimes, and the fix is usually pretty simple. I'd rather have a new guy learn to wrench on his own vehicle rather then go to the shop and pay an arm and a leg for a hack job with cheap parts.

what is the common problem or short with the #7 fuse for the instrument cluster? like where is the common short or what causes it to be a parasitic draw?

Usually caused by a faulty BCM (Body Control Module). It is located under the driver's side dash. Commonly needs re-soldered or replaced altogether.

I already re-soldered them, when I did a parasitic load test i only had .220mA but when I pulled the #7 fuse it dropped to .018mA so is there anything else other than the BCM that are normally shorted in that circut?

Brake light switch.

All four door modules.

Trailer tow circuit breaker.

Rear wiper motor.

Lift glass limit switch.

Speaker amplifier under the rear seat.

Automatic headlight sensor.

There's some things that are in that circuit.

Oh it definitely will. It answered so many of my questions that I had. The biggest thing right now is the cutting out/loss of power during acceleration.

alright just wanted to make sure, im not even positive thats where the draw is coming from, .220mA isnt an excessive draw, im probably gonna replace all the battery wires then if that doesnt help test all those circuts

Sounds very much like a faulty TPS (Throttle Position Sensor)
