VW Alternator / Generator Wiring Diagrams

Getting the correct wiring is essential for all your Electrical Parts. This guide includes wiring diagrams for both generator and alternator cars. All Volkswagens built in 1966 or earlier were originally made with a 6 volt generator. Many of those have since been converted to an alternator or a VW 12 Volt Generator. We do offer 6 Volt Generators for the early Volkswagen Beetle, Karmann Ghia and Bus. If you would like to convert to an Alternator, you can purchase a VW Alternator Conversion Kit here.

Generator Wiring:

Generators are wired to external voltage regulators. Note how the "D+" & "DF" terminals on the generator are wired to matching terminals on the voltage regulator.

Alternator Wiring:

Alternators have built-in voltage regulators so we modify our wiring to account for this.

VW alternator / generator stands support your alternator or generator as well as provide a location to fill your oil. Oil fillers are sold separately, and available in multiple styles to fit your car.

1 deflector plate and 2 stand gaskets will be needed for installation. Both gaskets to be installed, one on top of deflector plate, one below. You will notice 3 louvered "scoops" on the deflector plate. These scoops should dip down in to the opening, and the openings should open towards the passenger side of the engine block. This will help "deflect" engine oil back in to the engine case rather than help it exit.
