Hey all,

So today on the freeway I had a small under hood fire. The wires that go on the alternator post fried and caught fire. I noticed right before it happen that my rally pack oil gauge was pegged and figured it came off the sender and it did. I get the hood open and the wires were on fire so I ripped the negative cable off and stopped any real damage.
My question is since the oil pressure switch was not plugged in could that have caused my burn at the alternator? I don't want to replace wires just for the issue to not be corrected
I do have my electric choke going there as well but it's been wired there for some time with no issues .
I did have to jump the battery before I left but that was due to the glove box being left open and drained the battery i believe

 

The oil pressure wire is not the source of your fire. Its looking for varying levels of ground for the gauge to work. If you have an unfused wire for your choke which is B+ that could of caused it if it shorted. Chances are your issue is in the charging circuit.

 

The choke is fused. Any other ideas?

 

Can you determine which wire was the actual cause by separating the wires in the harness. As I stated previously the other cause is usually related to the charging system. Look at the 8ga wire off the stud on the alternator.
