140 amp alternator---great power out put

Summit RacingSummit Racing Verified Purchase

I upgraded to a cooling component fan and it required additional amps. I had a 100 amp pwermaster, but it could not keep up with air and an electric fan set up. the 140 amp has no problem at idle or at cruise speed. the alternator had a test tag that showed it was producing 92 amps at idle. they also included a 6 gauges charging wire with the alternator. Make sure you ground alternator for best performance. Very pleased with product and Summit Service. ...read more
