I have a 64 1/2 ton 230 3 on the tree . I took out my dash with the idiot lights and replaced it with a later model that has the gauge package . The harnesses matched up fine to the engine bay harness but i cant seem to get the d c gauge to work the truck came with an alternator but originally had a generator w/idiot light but the needle on the (brand new ) gauge doesnt move . Theres only 2 terminals for the gauge + and - . Also another thing happened was that i was getting a low voltage message (through my stereo) so i changed out my alternator to a newer one still the gauge dont work , could it be the voltage regulator giving me all the greif ? If anyone could supply me with a schematic to get the gauge working i would appreciate it thanks
