I'm planning to tear into it this weekend. So I'll post what I find out.

Yes, I have a few. 76 f250 (grandpa's old truck), 89 yj like the name implies (nuttered, google it!), 70 jeepster commando, 78 k-5 blazer, 65 mustang coupe, 99 gmc yukon (wife's daily driver and I hate working on it.)
Somewhere some little man is trying to control what other people do from his computer while still living in the basement of his mother's home.

Proper voltage while running will be around 13.5 to 14 volts. First check for battery voltage at the B+ terminal on the Alternator and the "A" terminal of the voltage regulator, if both have battery voltage disconnect the regulator and connect a jumper wire between the "A" and "F" terminals with the engine running while monitoring battery voltage. If the voltage jumps up "could go as high as 17 volts so don't hold it there long" this means the alternator is working and the regulator is a dud. If the voltage doesn't change leave the regulator disconnected and connect a jumper wire between the B+ and the fld terminals on the back of the alternator. If the voltage jumps up there is a problem in the harness. If not the alternator is bad.
