TRANSISTORIZED POINT REGULATOR
FIGURE 16. TRANSISTORIZED VOLTAGE REGULATOR.
Operation
This regulator operates essentially the same as the vibrating point regulator. The main difference is
that the contacts only carry a current that is used to trigger a transistor. Based on this signal
current from the points, the transistor will control and carry the field circuit. The advantage of this
configuration is increased contact point life, because the signal current to the transistor is low and
causes very little arcing.
