[QUOTE="los33, post: 8460655, member: 660834"] :| bunch of jibber jabber. No alternator's regulator has a cpu nor does a vehicle have a cpu. The auto sensing sensor is located either at the battery wire or near the pcm. The sudden drop in voltage during startup does not drop due to over charging. The regulator during cycle on reads the battery voltage + temp then calculates the max voltage producing a start up voltage. This warms up the alternator then it uses the same equation to calculate the nominal voltage for steady operation. Any oem ac delco or NG regulator maxes at 25v which then would cause the regulator its self to burn out. 45-50v would never be used as it would cause an electrical fire in any vehicle.
