RPM side drops power when lights turned on
Hey everybody!
My 1989 IROC has been acting up for some reason.
When I pull the plunger to turn the headlights on the whole right side of my cluster drops power. The rpm stays at whatever it was at when I turned them on, the battery gauge drops and the temperature gauge does as well and the right signal green light stays on. When I turn the **** on the plunger the dials move around as well. Sometimes when I signal right the dials will move up and down with the signal click.
Can somebody please help me. This is very annoying especially at night.

Re: RPM side drops power when lights turned on
Looks like possibly a grounding issue. I would start by cleaning all the grounds under the dash, and looking for any altered wiring from alarms, stereos, etc.... usually things like this are either corrosion or some previous modifications gone wrong.
