Connecting alternator for supply of lighting voltage to the grid
The two black wires from the Powerdynamo alternator carry voltage for lighting. They have no role in ignition.

This voltage has to be stabilised (regulated) and rectified (converted from AC into DC).

For this a rectifier/regulator is used. In this case a regulator part 73 00 799 50.
This regulator has been designed for systems running without battery and hence has a smoothing condenser inside to combat the effects of the remaining frequency in the DC voltage, but is may without reservation also be used in battery based systems, as long as this is a 12V lead/acid battery
Carefull: Any mixup in wires immediately destroys the part Same happens when you use in in positive earth systems (where plus is on chassis, this needs to be reversed!). Such events mostly result in the regulator developping some sharp, burnt smell.

  • the two black wires from the PD alternator (AC)
  • the red wire is the 12V DC output point
  • the bown wire is ground and also internally connected to housing
  • there is no option for a charge control lamp.
