Need alternator help - 83 Ranger

[RayInStl]

I finally have the Ranger running and driving well. The last issue to resolve is the charging system. I thought I had a bad alternator, but replacing with a spare that came out of a known-good truck has the same results. I was checking continuity from the alternator to the power regulator on the fender and I have continuity on the Field wire, but not on the Stator. My truck does have an ammeter, which seems to complicate the wiring a bit and I have to admit I'm lost. Should I have continuity on the Stator wire? If anyone has any troubleshooting ideas, I'd appreciate the help!

I want to say “yes”. But the correct answer is “Where are you measuring continuity to/from?”. It might be better, first of all, to make sure everything is connected and see where you do or don’t have voltage available.

The ammeter can largely be ignored. All it does is measure the voltage difference across the shunt. The shunt is a very precise, very small resistor. You will not likely see its resistance with most normal multimeters.

With everything connected, do you see full battery voltage at the stator terminal?

Have you seen the drawing for the system?
