Re: Polaizing the Generator

Is your generator not charging at all, or just not charging enough? Does your generator light stay on all the time? What causes you to think your generator needs to be polarized? Maybe your regulator is at fault?

I have a Delco system on my 53 Cavalier, but polarizing is the same deal, but terminals may be in different positions on the relay.

After I cooked my generator on a trip I had it rebuilt and then had a bit of trouble getting it charging again. These are the tests the guy that rebuilt my generator asked me to do. Maybe they'll be helpful??

hi its Art here,i was the one that rebuilt your generator...lets do a test which is quite easy to do,take these steps please

1.disconnect the field wire off the generator.
2-use a jumper wire and hook to the field term, than hook it up to a ground,this will tell you if the generator is working or not.
check the output,it should go to 8 volts and higher, if it doesn't than your generator isn't doing its job, i'm hoping the armature that i rebuilt is holding up.
3 if the generator is working ,than your regulator maybe giving you the issue.
4.you have a spare regulator, if that's your problem,switch them out,hook up all the wires to the reg,and polarize it,,you do this by taking a jumper wire and flashing the battery to gen connection on your regulator,,,
recheck charging system...if this doesn't help you may have to bring it back and ill have to retest and reset the regulator.

Thanks
