| Message: | Chris, I'll give this a shot: I, too, cheaped out and bought a rebuilt alternator. About 1,000 miles later, my dash gauge started going haywire. Needle jumping from charge to no-charge, alternator warning light going on and off, adjacent oil warning light right doing the same even though the oil was full. I figured it was the 30-year old under-dash connections, which many posts have warned not to mess with unless absolutely necessary, but to be safe I started testing across the battery every week or so with a multimeter. One day, though, everything just died. Weak charge across the battery, then dead battery. So, I figured it was time to re-do all the 30-year old connectors at and around the alternator, which visually were pretty bad. I had done the same with my starter with good results. I snapped everything off, put on new connectors, re-taped, and afterwards I had full charge across the battery terminals again. But, my warning lights are still on and off at the dashboard gauge, which shows that I'm charging about 9 volts when my multimeter reads about 13. The question, after all this, is given your bet that my rebuilt alternator is junk to begin with, have I simply applied a band-aid and will probably experience another charging failure? Or, does it sound like my dash-board is the culprit? Any way to rule in or out the dashboard? | ||||
