ryanb790,

As BIG CHEVY mentioned, how sure are you that the system isn't charging? A voltmeter on the battery is a good test. The in-dash ammeter is accurate if it's hooked up properly too.

Have you polarized the generator yet. With the truck OFF, momentarily jump the BATT terminal of the regulator to the GEN (or ARM) terminal of the regulator. This is done with a small jumper wire and should produce a small spark.

Your statement about have int eh generator built to a 12 volt configuration is interesting. Did the folks that worked on it have a history of doing this retrofit...you are confident that pulled it off properly.

You can perform a full field output test on your generator by grounding the field terminal to a good ground. Doing this for a moment will kick the generator into high gear. If you watch the voltage at the battery, you should see it climb into the high 13 or maybe low 14 volt range.

Dink around with it and see what develops. At night your headlights should go brighter as you rev the engine a bit. This shows the generator is doing at least some charging.

A functioning in-dash ammeter will tell you almost all you need to know about the health of the generator.
