: Need some help with gauges pegging when lights turned on

Hey all,

As the title says - when I turn parking lights or full lights on, my temp and fuel gauge slowly peg themselves to the right.

I pulled and checked the gauge pod/printed circuit, it looks OK. Nothing is crossed, worn, broken, etc. on the circuit. Gauges work perfectly UNTIL I turn the lights on.

Ground strap is connected off the headlight switch. There are no other grounds from the gauge pod to the car anywhere.

I need to know where to start looking and how to diagnose this - any help is much appreciated!

Problem solved -

Added a ground wire to the body from each "section" of the cluster (except at the light switch, which already had one) - works perfectly now! And, my dash lights got brighter, too....
