74 Duster trying to MELTDOWN!

sound like you have a power wire grounded somewhere. Or the car is not grounded did you reinstall the ground strap from the motor to the frame. if the clusteer is out check that the two main wires arent touching in the dash. One time I purshased three voltage regulators befor i got one that worked. But I would relly be looking for a grounded powerwire. A main wire or something. Good luck I would love to help if I was home.
