Hello everyone
Hoping to get some electrical help on my 72 It has a V8 in it but will not pass any power No buzzing of the fuelpump No dash lights No radio no horn nothing I pulled the ignition switch and tested it It was open until I turned the key and ohmed to almost 0 ohms When I released it open circuit Checked all wires in harness good Ohmed out every fuse in the panel below dash as well as a few in the rear of the car. Checked the ground strap (now a battery Cable) At first I was not getting continuity between the tranny bolt and the body Cleaned up the connection to the tranny as well as to the body ohms out to 2 ohms Checked the battery 12.5 volts Ohmed from neg terminal to chassis ground ohmed to 2-3 ohms It was running fine yesterday until i turned on the headlights while staring it then it died and I havent been able to get it to crank Any help would be appreciated thanks MIke |

Hello Everyone
Thanks for all the help. I pulled the NEG off the battery and dropped the fuse panel Behind it was a terminal block with the positive lead attached just as I was told. I only measured 3.2 VDC when the key was off and 0 when it was on. Puzzled I once again checked the fuses this time in the back of the car. I found 1 fuse that was a 30 amp. It tested good but was melted. I had to pull it out with pliers and thus destroyed it. Went to the auto parts store and picked up a new fuse. Took some emery paper to the contacts. Plugged her in and what do you know I have power and she is running again! You are the most helpful group of folks I know. Thanks very much! Mike |
