I was diddling around this afternoon and just changed my oil and was running the motor for about 5 minutes. This is a 96 LT1 car.

I inadvertently touched the ground coming out of the harness which is mounted to the radiator support to the drivers left of the radiator. This ground appears to come from the underhood fuse/relay box near the ABS. It was HOT to the touch.

Just for grins I opened the fuse/relay box, and all the operational relays (fans, ABS) were also hot (fans were on at the time). The metal area around the actual ground was NOT HOT.

Q1: Should either the ground, or the relays be hot?
Q2: If not, do you think making a better ground here (clean up and remount) will fix the HOT situation?

Back in the 'old' days, late '70's Firebirds had a bad habit of grounding the engin/tranny through the shifter cable. It would get so hot it would melt the casing, on some vehicles. The TSB kit included a new shifter cable and ground strap you ran from the tranny to the trans cross member.

Just a datapoint, but yeah, you probably need to add a ground strap. Almost anywhere from the engine/trans to the chassis.
