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?

Bolt it to something solid with a good clean connection on the chassis. Then most of them go to the edge of a cylinder head (front or rear) or other similar location. On top of the engine lift plate on the intake (above the plate, under the bolt), etc.

If the LT1 blocks have a fuel pump boss on them (I don't think they still do), you could bolt it on there and then to the chassis.
