Hello,
So over the winter I re wired my entire 1970 roadrunner with the factory matching wire harness from M&H electronics in California that Year One sells. Did so after finding out some previous owner did some hack job far under the dash and some plugs were falling apart being 48 years old. So not too tough but took some time. Any how, new gauges, new wiring, new rallye gauge circuit board, new temp sending unit and temp gauge won't work. So if I put a grounded wire in the engine plug that goes on the temp sending unit and turn ignition power on the gauge goes all the way up then back down searching for a temp so as best as I understand that means the gauge works? But still run car for awhile and gauge never moves. All the other factory rallye gauges I installed all work fine. Ideas, maybe defaulty new temp sending unit?
