I have a friend that redone his 70 RR and bought a NEW wiring harness from Year One, he had his gauges all redone by RedLine gauges, and everything is new on the car.
His problem is when he turns on his headlights all his gauges go to the bottom, like he turned off the key. He needs an idea of what to look for as like said before Everything is New or has been Redone like New. We are not very good at wiring issues.
Any ideas would be Greatly Appreciated.
could it be a ground issue somewhere???
Thanks David
