Here's my wiring around the steering column. I've tried to test the orange/red wire with no luck. I can't find voltage anywhere.
Sperry digital. I could have had it set wrong. A/C, okay. I'll check my ground too. And read my annotation on the first attachment. I have the required ohms in each grip.What kind of voltage tester did you use? Check you ground with a ohm meter. This will be A/C voltage to lights etc. Hard to believe all heater elements went bad at the same time.
