Swapped to Muscle - 75 Duster Daily build

The housing grounds to the dash frame, that's why you don't see a ground. Usually people have problems because they plug everything in to test it and don't screw the cluster down and then nothing works. But if you did a temp ground, then that shouldn't be the issue.

Also remember that the amp gauge has to be hooked up to try anything. Without that, there is no power in the car. I've bolted the amp gauge wire ends together before to test stuff, just remember they are always hot and should be wrapped just so they don't accidentally spark.

Guessing it is the voltage regulator, the three pin push in thing at the middle top. Pretty sure if that goes, none of the gauges work, but not absolutely certain. I might have a spare, or you could build a solid state one for a couple of bucks and avoid issue down the road even if it doesn't fix this one.

Reminds me that I might need to look at my regulator, might fix some of the issues I am fighting with.

Yea, I did two separate bypasses. I did the bolt through both the ends of the wires of the amp gauge (you can see it in the picture) and also, i did run a wire from the Alt to the starter solenoid as well with still gives power to the car (this is my temp wire to get the car power initially that I have not properly fixed).

Is this the voltage regulator that you are referring to?
