I had several GM alternators converted to 6 volts. The electric
motor company, Chestnut Hill Electric near Lancaster, Pa. suggested
they use a 24 volt stator and 6 volt diodes and an adjustable
voltage regulator. This allowed it to provide 7.2 volts at idle with
a LARGE 39 Ford pulley. On the 7 alternators I made the adjustable
voltage regulator was mounted inside the rear cover plate with a
hole through the cover plate to adjust the idle voltage. I had two of
them made 10 or more years ago and they still work good. We used
a 39 Ford front generator mount with the big bearing and had to
make a shaft adaptor for the front of the shaft for the pulley to mount
on. The last picture shows the long term end results of an over tight
fan belt. This pump was of a 35 Ford that belonged to a friend of
mines father. The two end covers were 2 of seven alternators I made
a number of years ago and all seven still work good. G.M.
