Hello
My 1924 stock T Model Coupe's generator (6 volt system) puts out 6-8 amps at regular road speed (30-35 mph). Last week in about 15 mile drive it went from 6-8 amps to the max on the gauge of 20 amps.The volt meter I have on the car went from 7-71/2 volts to almost 10 volt reading. I adjusted on the Third Brush which did not change the out put of 20+Amps or the Voltage reading.
ANY suggestions will be Appreciated!
THANK YOU---David H

Re: Generator Needs HELP
I think you have short in your Generator.
It will need a good overhaul.
Good luck

Re: Generator Needs HELP
The brush plate is held in place with 4 very small screws, almost sounds like that plate has come loose. Can you move the whole plate, with the 3rd brush still tight to it. If the brush plate has come loose and none of the 4 screws are missing read the section in the Ford service manual on in car set up of the brush plate.
I know the voices aren't real but damn they have some good ideas!

Re: Generator Needs HELP
It sound to me like the wire connected to the output that goes to the battery is shorted to the field winding that is normally supplied by the third brush. You can test for a short buy putting little strips of cardboard or paper between the brushes and the commutator and then use an ohm meter to see if the third brush and the output brush are shorted. Look for frayed wires.

Re: Generator Needs HELP
I think I will try the adjustment on the Brush Plate.If no luck with that I will see if I can find shorted wire or field coil
Thanks --David

Re: Generator Needs HELP
The 3rd brush insulator can be problematic after years of fiddling by "who knows who" !
