tristan watson 2 #1 Posted January 31, 2018 Ok I tested my stator the other night because I didn't think I was getting any power and out of it and it's working fine now I hooked it back up to regulator rectifier this is one that is installed in the lower dash and when I start the engine it's throwing out a lot of Sparks and was wondering why it would be doing this and how to fix it?

Ed Kennell 35,146 #2 Posted January 31, 2018 Where are the sparks located? Several possibilities are : one of the AC wires is shorted to ground inside the flywheel the AC wires are not on the AC posts on the regulator the regulator is not grounded to the tractor. the regulator has melted and the AC wire are shorted directly to the DC battery wire 4 Share this post Link to post Share on other sites
tristan watson 2 #3 Posted February 15, 2018 The sparks are coming from the mount plate for the regulator rectifier and voltmeter Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,444 #4 Posted February 15, 2018 The body of the regulator must be grounded and due to oxidation and corrosion the chassis metal the regulator is mounted on is no longer providing a consistent ground back to the negative battery cable. Best fix is to add a ground wire to one of the regulator mounting bolts and connect the other end to a known good ground. Garry 2 Share this post Link to post Share on other sites
953 nut 51,018 #5 Posted February 15, 2018 (edited) Garry's suggestion will probably solve the problem. I have always found that with any electrical problem the first thing that must be done is clean and tighten all electrical connections including grounds.

tristan watson 2 #6 Posted September 14, 2018 so could i just run the ground from the rectifier directly to the post that grounds the battery to the tractor? Share this post Link to post Share on other sites

Yes. Either end of the negative battery cable. Garry Share this post Link to post Share on other sites
