electrical short

1987 S15
no taillights
when I turn on taillights, the gas gauge goes to empty.
When I turn on blinkers, the gas gauge goes to empty and both taillights and license plate light flash.
Any ideas?

Run a temporary ground from a KNOWN good ground (I use battery) and see if it suddenly improves. Frames and pickup beds all make bad connections after a while.

Bad bulbs will do weird things to electric circuits. Check those grounds too. Swap bulbs from side to side and see what happens, remove them one at a time and see what the gas gauge does. It could be a short in a wire under the dash, got critters in your garage?

There is no factory connection between the gas gauge circuit and any of the light circuits. Change all the bulbs you want. That's not the cause. This is most likely a pinched wire harness somewhere between the dash and the back of the car. There's a short somewhere in the harness that is tying these circuits together.
