What should the voltage be on a VW generator?
Use a jumper lead to connect DF to the generator frame (grounding the DF connection). Now start the engine and test the voltage between D+ and the generator frame. The voltage should increase with rpm up to about 35 volts (20 volts or so for the 6-volt generator). If the generator passes this test]
What kind of voltage regulator does a VW Beetle use?
Voltage Regulator, 6 Volt Generator Models, Bosch, 30-020 is a new 6 Volt voltage regulator for VW Beetle, Ghia, and Bus. These are getting REALLY tough to find! Unregulated Generator output is over 9 volts, and regulators charge the battery when it needs it, and more importantly doesn’t when it’s fully charged!
What should the voltage be on a VW Charger?
Disconnect the generator from the regulator (both the DF and D+ wires). Use a jumper lead to connect DF to the generator frame (grounding the DF connection). Now start the engine and test the voltage between D+ and the generator frame. The voltage should increase with rpm up to about 35 volts (20 volts or so for the 6-volt generator).
How to know if your generator is charging?
Now start the engine and see if the ammeter swings postive, indicating that the generator is charging the battery. If not, connect a jumper wire from the F terminal on the regulator to ground. If it charges now, the regulator is faulty or out of adjustment.
What kind of battery does a VW Beetle need?
The VW Beetle is an easy starting engine and needs only a low CCA rating of about 220; the VW engine, being a lowish compression engine, is relatively easy on batteries.
Where is the alternator located on a VW?
From 1967 until 1974 it was located underneath the rear seat on the left. From 1974 on the voltage regulator is internal to the alternator. If the 6-volt Bug has been converted to 12 volts, the 12-volt regulator is usually screwed to the fan shroud just above the generator so the existing wiring can be used.
What does a voltage regulator do on a VW?
You’ve got a problem. The electrical system on 6- and 12-volt VWs up to and including 1972 used a generator to produce power, a voltage regulator to set the charging level, and a battery to store the power. The voltage regulator is used to adjust the current flowing through the field windings (the stationary outer windings) of the generator.
