on the generator. The generator then supplies current to charge the battery and operate vehicle accessories.
As generator speed increases, the voltage reaches the preset value and the components in the regulator cause
transistor TR-1 to alternately turn off and turn on the generator field voltage. The regulator thus operates to
limit the generator output voltage to the preset value.
Never short or ground the regulator terminals; DO NOT attempt to polarize the circuit.
