Default generator issues

hello friends, today i found out my stalling problem was due to my generator.

My battery is only testing at 12.5 while running and not receiving a charge from the generator. even at 2000 rpm it reads 12.5 and lower.

I've tried polarizing the generator but it still wasn't making a charge.

HELP lol

Check your brushes, it's most likely your problem. You need have an excess of a 1/2" in brush length. I have to change mine every year or two depending on mileage, the after market brushes don't seem to last as long as ome. If you are unsure of the process there is at least one thread on the process in the sticky section.

Here's the link to the sticky mentioned by Ironhead78.

http://xlforum.net/forums/s...ad.php?t=39146

Checking the brushes is a good idea, use the procedure in the sticky to find the problem if the brushes are good.

Have you done the output tests as mentioned in the sticky by Yellowstone Kelly? That's the only way to verify the issue. When my bike had a bad regulator it never charged either, but the gen. was completely fine.

So i got the generator off and tried to hook it up to a battery to see if it will spin. But it wont spin does that mean it is bad?

Did you do it this way, with good grounds?

9. Here's a good way to bench test your generator:
Contributed by Bowtied

1. connect a jumper from the "+" battery post to the "A" armature terminal on the gen.
2. Connect a jumper from the "-" battery post to the "F" field terminal of the gen.
3. Now take a third jumper from the "-" battery post and touch it to the case of the gen.

If all is well the generator will run like an electric motor. With the gen gear pointing away from you the rotation is clockwise.

Okay it worked so does that mean i just need to clean my brushes and stuff?

Or would a bad regulator keep it from charging as well

Can't comment on your brushes and stuff. Haven't seen.

But a bad regulator could stop voltage to battery or give it way too much.
