Guest butlersZ Posted November 6, 2003 Share Posted November 6, 2003 Is it possible to eliminate the external voltage regulator on a '74 260? Since the alternator has a built in regulator... I know the function of the voltage regulator is to charge the battery when it needs it, but then what is the regulator on the alternator for? Could I eliminate the external regulator and switch to a different alternator maybe? The reason I am asking is because I was running around last night in my Z for about five hours in the dark with the heater,headlights, and driving lights on and after awhile the dash lights became dimmer and dimmer as well as the headlights. The battery wasn't charging or maybe the alternator wasn't putting out enough power, anyway I took the car to Kragen and they tested the car and said there was no charging voltage, so I pulled the alternator and they tested it on thier machine and it puts out 16 volts, so they suspected the regulator. I really want to get rid of it or maybe make my own regulator somehow, is this possible? Need help fast before I go purchase a damn regulator.

Guest Aaron Posted November 6, 2003 Share Posted November 6, 2003 Are you sure your alternator has an internal regulator? 16 volts seems like too much for it to be. The regulator's job is to smooth out the voltage created by the altenator. I have always seen around 14 volts. If the charging system is generating too high voltage, you will overcharge your battery which will ruin it or cause it to explode ! If id does not build enough voltage, it will drain your battery, and eventually ruin it. In your situation, I think you need to replace the regulator, or buy an internally regulated alternator and rewire your car to use it.
