To determine if the alternator is GOOD, "full-field" it (for a short period of time) by pulling the connector off of the back, and jumpering the terminal labeled "F" to the large output stud on the back of the alternator. This will make it charge at it's max output.
Before doing the jumper thing, check the voltage at the large output stud. Without the alternator charging, it will be around 12.5 Volts. When you install the jumper, if the alternator is working, the output voltage will quickly come up to 16 to 18 Volts, or even more.
Use an ANALOG meter, as many digital meters are "freaked out" by the "noisy" electriacl systems on these old machines.
