I had a friend whos had a 1973 coupe deville wit the same problem and he said its the postive wire under the car some where ...can anyone tell me if this is correct and where thanks email calvdaley@aol.com

 

Hey Model: Put a digital amp. meter on the battery, you will obviously see the amps dropping little by little. Pull one fuse at a time until you see the amp. drop stop. You will then know which circuit you are dealing with. Trace all the wires from this circuit and all the grounds for this circuit to make sure all grounds are good and all wires are not frayed and shorting out. It will take some time but will save you a bundle. GOOD luck.
