Stop in for a cup of coffee

Good morning;

I'm having issues with my temp gauge on my 68 cuda. It's always pegging to the H. I heard there may be a faulty relay of some sort. Is that true? And where is it that l might change it out?

Could be the voltage limiter on the back of the gauges not grounding properly or going out...

Have you downloaded a copy of the service manual yet??? Electrical diagrams in the back of chapter 8..
