Has anyone had problems with their charging system running underdrives? I'm hoping that it's related to my alternator power wire being hacked up so many times. I have a new wire on the way (discontinued by Ford by the way). I checked it with my voltmeter while it's running and it's only putting out 12.?? volts. When I had the stock pullies on there it was closer to 14V and didn't have any problems. I think I may be taxing it too much by running and IC fan and my low speed fan all the time in the summer. Anyone running extra accessories with underdrives with no problems? Can I get a better alternator than stock?
