What would be reason for 1980 F-100 not having power after replacing battery?
Replaced dead battery in 1980 F-100 because no power. Still won't power up any lights, etc.. let alone turn motor over. Replaced starter - relay but still can't get power to elecrical system for some reason. Even tried to jump start from another vehicle. Not sure wht direction to go in.
Short in the system?? Alt. maybe
The early 80s ford have an issue with bad grounds, check the neg. cable from battery to block.....
TShot ..could never be an alt.... with the symptoms described...
I had a similar problem in my 1980 f100, I replaced the battery cables and that gave me power back
You might check the ignition coil too
