I recently had my 383H.O. rebuilt in my 1969 Charger. At first only my headlights were dim but now I have no power to anything; Head lights , interior lights ignition switch or tail lights. I have a fresh battery. Sounds like grounding issue but not sure where all the grounding points are. Any info would be appreciated. Thanks

 

Did you check the bulkhead connector going threw the firewall? The terminals have been known to get corroded/heat up. The ground cable should go to the drivers side head. You should have another going to the body from the engine or from the battery.

 

I'll try to check this out this weekend, Thanks
