generator or voltage regulater
ok than the other morning i woke up and went to start my truck and it was dead. i made some calls to find out how to test if it was my generator or voltage regulator. i was told that if i unhooked the A and the F wires from the generator and than started it up and than took a test light and tuched it to the A terminal on the generator it would light up when you reved it up if it was good and not if it was bad. is this the right way to test it? well i did that and it never lighted up so i sent it away to be rebuilt. i got it back and hoocked it up and it still is not chargeing so it must be the voltage regulator. i no its not the battery. the thing i need to no is this the right way to test the generator so i can test the new one and make sure that its working. also to polarize it i take a jumper wire and touch it to the batery wire and Arm. wire at the voltage regulator? right? its on a 59 if that makes any differnce any help would be awsome. thanks

HI 59!
To test the output of the generator with generator on the engine: Disconnect the generator "ARM" and "FIELD" wires. Connect a jumper wire from the generator "ARM" terminal to the generator "FIELD" and the negative lead of a 0 to 50 ammeter to the generator "ARM" terminal.
Start the engine and immediately connect the ammeter positive lead to the battery. Run the engine at 1500 rpm and read the current output on the ammeter. The generator output should reach or exceed 35 Amperes (60 amperes an 8BA-10002-C generator).
Once the regulator is polarized you don't have to do it again.
But the procedure for doing it when you install a NEW Voltage Regulator is to:
Disconnect the "FIELD" wire from the regulator and touch it to the "BATT" terminal of the regulator for a millisecond. It will probably spark at you a little.
Here's a very good link on the subject if you want to fool with test set-ups and spending a lot of time taking measurements. But bottom line is, if the generator is producing, and you know for a fact taht your battery is good then the only problems left would be wiring or the regulator.

Yes. The polarization is a charge in the coils of the regulator and it stays that way perminently unless you "demagnetize" it somehow.
Looks like we are both on the link at the same time. I edited my first post a little while you were writing...check it out!

well it fixed it but the only problem is that the generator light wont come off but its puting out about 13 volts when its idealing but when i reve it up it goes to 14.5.
