Gregor 4,846 #26 Posted April 24, 2021 I obviously have something wrong. As soon as I let go of the key, I lose the 12V going to the coil. I need to do some more checking. Share this post Link to post Share on other sites
pfrederi 17,741 #27 Posted April 24, 2021 If you have a 4 terminal regulator and you followed the WH wiring diagram you are missing a connection. Bottom terminal of regulator to A on the genny. (It was a Kohler part and isn't on WH diagram) Share this post Link to post Share on other sites
Gregor 4,846 #28 Posted April 24, 2021 NOOOOW it's wired according to the book. Share this post Link to post Share on other sites
pfrederi 17,741 #29 Posted April 24, 2021 That looks correct. Now if it doesn't charge Ground the Field terminal and see if it starts charging... Share this post Link to post Share on other sites
Gregor 4,846 #30 Posted April 24, 2021 With the tractor running 2.6 V F terminal on generator 0 V A terminal on generator 2.6 V F terminal on VR 12 V Battery terminal on generator 12 V Lighter terminal on generator The generator warning light is lit, but the cigarette lighter works! I am going by the diagram in the book, but I don't know how to post it. Share this post Link to post Share on other sites

pfrederi 17,741 #32 Posted April 24, 2021 hold it there for 10-15 seconds see if voltage on battery goes up Share this post Link to post Share on other sites
pfrederi 17,741 #33 Posted April 24, 2021 (edited) This one?? This is the one missing the Kohler installed wire which you seem to have now Edited April 24, 2021 by pfrederi Share this post Link to post Share on other sites
Gregor 4,846 #34 Posted April 24, 2021 Yes I have another wire from VR to A terminal. Battery voltage stayed constant. 11.97 V, but the starter works good. The little light went out, and the bulb is good.. I checked it. Share this post Link to post Share on other sites

He!!, I gotta start over. ! Nothing on any F terminal. slight voltage on A Edited April 24, 2021 by Gregor Share this post Link to post Share on other sites
pfrederi 17,741 #36 Posted April 24, 2021 The field wire is a variable ground I have no idea what if any voltage you should see. If you have it wired correctly and there is good ground ( I know you paint and powder coat a lot., looks nice but. terrible for grounding) make sure your V/R mount and the generator body are well connected and grounded. then it should start charging when you ground the F terminal. If not the the charging field coil in the generator is likely bad. Share this post Link to post Share on other sites
Gregor 4,846 #37 Posted April 24, 2021 Ya know, for the 6 times a year this tractor MIGHT get started, I'm not going to worry about it right now. I really wish it were working, but it's not. I have it tore down, doing some paint touch up. When I get it all back together, I will bolt a SPECIFIC ground cable to it, and see if that helps any. so much for all your help.

Gregor 4,846 #38 Posted April 24, 2021 I did scrape off some paint from the generator mounting bracket, ran a #8 wire directly to neg on the battery, didn't help. Share this post Link to post Share on other sites
