I am going to look at an issue a local guy is having with his 73 Road Runner, I have never seen the car before or met the owner but I was contacted by him through a mutual friend. He is having an issue with some of his dash gauges, he said the Fuel Gauge and Oil Gauge is pegged to the full or high side and I believe the Amp gauge is too, he said the tach isn’t working properly. The car is supposed to have a new dash harness and the factory style tach isn’t original to the car but it is a rebuilt unit from Year One and it has a new harness on it. He said he has checked all the grounds already and tried moving the ground wires to make sure he has a good ground and he said they seem fine, but he still has the issues. Any ideas of where to start with this one before I go over there?
Thanks.
