Topic: 1936 ford 12 volt starter reduce revolutions


tpenty1    -- 01-16-2021 @ 7:19 AM
  After converting my 1936 ford to 12 volts I installed a 12 volt starter. After less than 2 years the Bendix brock at the thread attachment to the starter body. Is there a shunt or resistor I could use to slow down the revolutions? Thanks.

  Are you sure that the starter was 12 volts? A 12 volt starter would spin just a little faster than a 6 volt starter in a 6 volt system and should not break the Bendix. Use a 56 or 57 Ford starter or have 12 volt field coils put in yours.

The starter draws 150-200 Amps, so you would need a 2,000 watt resister to drop the voltage and it would have to be mounted on a heat sink to dissipate the heat.

  hi tpenty1
you could contact CERTIFIED AUTO ELECTRIC in OHIO
PHONE 440 439 1100 or 6vto12v@gmail.com
they helped me in the past,
hope this helps, 37Ragtopman

I had them redo a starter using a high torque field coils , and I had a nos 6v ARMATURE
and it works just fine with out going to 12 volts,

  It is a 12 volt starter from Mac's installed with an original Bendix because the modern Bendix a bit larger in diameter would not fit in the flywheel housing. I was concerned about burning up the six volt. I am concerned about how hard the Bendix hits the flywheel and maybe why it broke.

  Do you have the starter support bracket that attaches to the oil pan installed??

  Get a new old style Bendix from Mac Van Pelt: http://www.vanpeltsales.com/FH_web/FH_images/Igntion-Partspics/B-11350starterdrive.jpg
