Hi I haVe a 68 road runner and I'm having some electrical issues, I think its a ground problem. It seems sometimes things work and then they don't. Wipers will work periodically, same with blower motor, brake lights, and turn signals.I'm thinking I have a ground problem can anybody give me the locations of ground locations to check, also fuel Gage does not work, new sender installed gage reads e when in tank when I pull out and move float it will work correctly I have the ground clip on the fuel line and checked to make sure its grounded and it is but still reads e.
Any help would be appreciated.
