Re: voltage problem

You want to know the generator is properly wired to the regulator and the rest of the car. Keep in mind the power supplied from the generator comes from the armature.

They say do not connect radio noise suppression capacitors to any terminals on the regulator or the field connection of the generator.

The regulator regulates voltage output first as long as the current is in the proper range.

The regulator pulses the field winding by rapidly opening and closing the contacts on the voltage relay in the regulator.

If you have a voltmeter you would expect the voltage to be close to the 7.5 on the armature connection but the field will vary depending on the load and it will be a pulse waveform and be difficult to read with a digital type meter.

You would want to be ready to measure the voltage coming from the Armature terminal of the generator when the problem occurs.
