As it says in the title my AC compressor plug wires got burnt. The plug is fine and the wires are basically fine, but there's this thing on the wire and I don't know what it is. I was doing some belt work and accidentally left the AC plug undone and hanging by the exhaust manifold where it proceeded to melt the inline capacitor/resistor/thing. I haven't plugged it in yet because I don't know if it's bad that this thing is busted. I haven't found any good wiring diagrams of it either. Again the wires are fine around it, its just this piece that is inline on I think the black cable.

 

Yikes! Did the wire insulation wear through and give you a short to ground? Or a rat chew through it?

 

He said that he left it hanging by the exhaust manifold.

 

I would think you can just splice new wire in

 

Clearly I need to read a bit more thoroughly

 

Maybe a previous repair? It's just 12V supply to pull in the clutch, just cut and replace with some 12-14ga wire. Should be fine.

That's some unique intake piping BTW. I mean, lots of us delete the throttle body heater, but we tend to keep the throttle body itself.

 

Hahaha the intake routing on it is a little funny, I LS swapped it using Alternative Conversions kit. It worked out great and I have a couple thousand miles on the new engine. I looked again and pulled it apart and found something interesting. There appears to be a little diode connecting the two wires. It has the lettering ln4006 and below it 832C. I googled it and found it to be very similar to this. It doesn't appear to be damaged by the burn, it's just weird it's in there. Just wanted to throw this out there before putting it back together

EDIT: found this on a chevy S10 forum:
"The diode you found in the a/c clutch circuit is a spike-suppression diode, attached to the compressor clutch terminals to eliminate the potentially damaging voltage spikes that occur each time power is removed from the compressor clutch and the clutch opens. If there were no diode in the circuit, these voltage spikes could travel through the circuit, possibly damaging other components and introducing "noise" into the vehicle's electrical system, at the very least."

It looks to be stock land rover wiring and everyone should have them on theirs.

 

I plugged it in and found that it worked fine, the diode didn't have any damage from the exhaust burns. Turns out my problem was a non problem, just learning about what is on the truck. I used some shrink-wrap, electrical tape, and corrugated loom to cover up the wires. I probably should've used some wiring loom cloth fabric, but this is what I had on hand.

 

I mistakenly cut this connector when doing my LS swap and you saved me a lot of grief and time. Thanks!
