RevyAjax 3 #1 Posted June 5, 2017 I put a new starter on my C-100. It is spinning the wrong direction and will not throw out the bendix to the fly wheel. Can I reverse the direction of the starter somehow? Share this post Link to post Share on other sites

I wondered about that...just tried an experiment with a battery and spare starter motor. You are right. Reverse the lead and it spins the wrong way. 3 Share this post Link to post Share on other sites
WHX?? 46,405 #4 Posted June 5, 2017 Basic DC theory Paul, I was also going to suggest somehow the brush/field polarity is reversed in the starter but not sure if that is even possible? Share this post Link to post Share on other sites

I wondered about this as it is common to switch old farm tractors from positive ground (popular in the 40s/50s) to negative ground. It did not require changing eh starter motor or the genny (just re-polarize the generator. Permanent Magnets!! Kohler starters have them old tractors did not. (Hence the stickers "Do not pound on the starter" 2 Share this post Link to post Share on other sites

Reverse the lead and it spins the wrong way. Important to remember and for younger members to label starter wires when all cables are the same color. Share this post Link to post Share on other sites
