I replace the alternator in my Bronco tonight and took my little Bronco out for a drive. When I took it out for a test drive to make sure that everthing was ok the lights at first was very bright then all the sudden went dim then went bright back to dim. The voltage gauge was jumping back in forth to 0 to 60? So what could it be? I am thinking that it could be my regulator going bad or is it some kind of grounding? I replace the ground side cable from the battery to the engine.. Please HELP.....
