OK, here's the quirk: My 1982 GS had the gauge cluster changed out by the previous owner. Why, I do not know. Anyway, the temperature gauge usually reads at 1/4 with normal driving, varying only slightly. When the lights are turned on, it rapidly climbs to 1/2 or a bit over! Even when the turn signals are on for a few hundred yards. Could this be a ground problem? Should I install an aftermarket temp gauge? Let me know what you experts think this might be because I am thoroughly confused. Thanks!

It does sound like an electrical issue. Do you notice a drop on the volt meter when the lights are on? Just trying to see if you have an alternator problem or something like that.

An aftermarket gauge would be a nice backup to have even if you fix the stock one.

There are sections that show how to test the gauges to see if it is a problem with the gauge/sender or something else.

Good luck.

Thank you Kent! I am on it getting the aftermarket gauge...any brand recommendations? With 2000 feet to climb coming in from Temecula, I really want to make sure the engine is cool and I know what is really going on.
When I drive the car next time, I will observe the volt meter gauge...
