All this week I have been rebuilding the original generator for Nellie. This was my first experience working on a generator and it wasn't so hard. Luckily the coil windings were good. I turned down the commutator slightly, undercut the mica insulation, installed new bearings and bedded the brushes.
I did the test to find neutral and installed it into the car. Then I adjusted the third brush with the car running. I was conservative with setting it to charge at around 8 amps when driving at around 20 mph. I was amazed that everything worked well including the 90 year old ammeter.
At first I wondered what the hell that weird whirring noise that I was hearing at certain speeds. Have never owned a T with a starter and generator .... strange. The engine has a NOS iron timing gear ... so I guess it's the loudest possible combination.
Now you're ready for a FP VR.
No what mark needs is a top on his car before he freezes on the next ride
Well ... yes, I said mechanically complete. :-) Restoring the top is this winters project.
Mark, if your generator gear is making too much noise, perhaps you could add a thin gasket. That will move the generator away from the timing gear.
