How does a VW voltage regulator work?
The regulator controls the voltage/current fed to the rotor’s electromagnet coil windings through terminals D- and DF to provide an output voltage at the D+ or B+ terminals of about 14.5V. When the regulator is working normally D- is connected to ground and around 6V is applied to terminal DF.
How do I know if my Harley voltage regulator is bad?
Bad Harley Voltage Regulator Symptoms
- Power Failure. One of the simplest ways to notice a bad Harley voltage regulator is when the cluster cannot power.
- Gauge Flickering.
- Malfunction in engine light.
- Error reading the cluster.
- Brown headlights.
- Gas fusing out of battery.
- Faulty voltmeter reading-
Where is the alternator regulator on a VW Beetle?
Testing and Repairing Regulator- early alternator equipped Type 1’s (1973-1974) Early alternator-equipped Beetles use a Bosch alternator with an external regulator (BOS-0-190-600-017) screwed to the left wall under the rear seat.
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.
What’s the charge indicator on a VW Beetle?
When the regulator is working normally D- is connected to ground and around 6V is applied to terminal DF. For the past year I’ve had problems with the charge indicator warning light coming on intermittently. I eventually found that giving the regulator a sharp whack would make the light go out- for a while.
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.
