It may now be wedged or somehow stuck in the slip ring and require removing the generator to fix it.

Re: generator third brush adjustment need help
Recently I had the same problem, turned out that the wire off of the output stud got hooked on one of the fields, I got an old button hook and snagged the wire and in two minutes I could adjust the brush down to "0".

Re: generator third brush adjustment need help
When the cars were new, did the driver push the brush down when he was going to drive at night as a regular routine or did the brush just get left there all the time?

Quote:
If you read the Ford Service Bulletins, they advise the dealer to adjust the charging amps up in the fall, prior to cold weather and more night driving. They advise them to adjust the rate back down in the spring. It was not adjusted on something like a daily frequency.

Re: generator third brush adjustment need help
Have solved my problem. I took a screw driver and carefully with a
Hammer tapped it back. Did not tap against the Brush assembly But on the edge on a metal part Fredski |
