Gauge grounds get hot

I have a fiberglass car, and I just finished wiring it. I grounded the gauges, and when I went to start the car the ground wires got super hot. I'm using mechanical gauges and the same gauge wire that the harness has. I show that I'm getting a good ground when I use the meter. I also do not see any positive wire touching the gauges (thought a positive and negative were touching).

Suggestions?

How many gauges are you running through the one ground wire and what gauge is it. If you are running mechanical gauges what aer you grounding with this wire just the lights?

one ground lead for every two gauges..14 gauge wire. I added a couple ground straps to the car, and it doesn't get hot now.

re

Something else is grounding through your gauge ground, probably through the lighting circuit. Disconnect the ground and see what else does not work anymore

Exactly, these are the things that car fires are made of
