Alternator Charging

When I start my car it will show approx. 12 volts it will stay at 12 volts for a while until iI rev the engine, then it will jump to 14 volts. This is no real problem as the car always starts and when you rev it up it does put out the 14 volts, I was just wondering what would cause this.
This is in my 55 wagon with 454 engine and 3 wire alternator.

Doc here,

Check your small red wire at the plug on the top/side of the alternator..IF it is jumped to the large red (power output) wire, extend and move it to your horn relay POWER, or switched , fused source at the fuse buss..

This will give you remote sensing, and allow the regulator to turn on sooner and run longer at the same RPM..

What system DO you have..?
  • 3 Wire , Internally regulated SI series?
  • 3 Wire Externally regulated SI Series?
  • 5 wire CS series alternator?
