Bronco charges battery with each start up for a few min then quits charging, next day it will charge the entire drive time. Next day only for a few min. then periodically charge. I have read several post that state diff. Ideas but I still can not seem to fix problem. Have not replaced Alt. due to I read that it works or does not,plus it is a PITA to get off due to the EFI Exhaust on the 300(converted to EFI over stock). I have checked all connections, replaced under dash servo. nothing seems loose, any help will be welcome.
