Not Charging, pulling my hair out.

If the above test shows an increase in voltage at the battery, that is "shows charging" Move on

Now, hook up the switched ignition wire to either field. Key on........engine off.... Set your multimeter for high DC current. Hook it between the remaining field and ground. You should read 2-3 or more amps draw

If you have no multimeter, again with key "in run" use a clip lead in reduced light, and ground the remaining field. You should see a small spark.

Clip the lead to ground, start and run the engine, fast idle, and watch battery voltage

If you see an increase, so far so good.

=========================================================

Next, remove the VR connector and devise a way to jumper the two terminals togehter at the connector. Machine screws work.

Hook the "would be green" from the VR to the alternator to one field. Clip the other field to ground

Repeat, run engine see if it charges

If so, the field wiring is all good, and the alternator is working

=========================================================

The VR ABSOLUTELY must be grounded MUST. Clean it, mount tight, use star locks. "Jack" the connector in/ out several times to feel for tightness and scrub the terminals. Inspect them visually for corrosion.

Hook all up normally and test. If no charge, replace the VR
