Generator problems...still.

[davidg8991]

My generator is still giving me fits. Been repaired 3- times for different issues and still can't seem to make it work.
Just got it back this time and their is the new problem!
Turn the key on and the GEN light comes on. Start the engine and the light goes off on idle, but, as I rev-up the engine the light comes on, and the higher the RPM,s the brighter the light. I am not sending it back for a 4th time. Hoping I can fix it myself.
Note: Yes I did polarize the generator, correctly! My procedure was as follows...With the engine not running, connected a jumper wire from the "BATT" terminal at the voltage regulator and the Armature terminal on the generator for approximately 1-second. Just to be clear, the Armature post is the one "CLOSEST" to the engine, correct!
I thank all of you for your time in this matter.

Have you checked the voltage at idle and as the rpm rises?

And checked your voltage regulator for correct voltage regulation and ohms?

Jim's got a good idea.If the charging drops off as the rpm's go up,either the brushes are losing contact or the armature is shorting out.If the voltage drops of gradually,it's brushes most of the time.

I have a new voltage regulator on hand. Will try it tomorrow. Thank you.

Will check the brushes as well. Thanks.

Where's a growler when you need one? Or some good ole testing with a volt meter anyway.

It was the voltage regulator, . Thank you for all your help.
