On this style regulator there is a terminal on the bottom. That has a short wire that runs directly to the armature terminal on the Genny. There are two wires on the genny A post one heavy one for starting and the lighter one for charging via the regulator. It doesn't show up here as it is actually a Kohler part and is shown in the Kohler engine parts manuals and came with the engine S/G unit. . This diagram is a Wheel horse diagram it only shows the stuff they added. Good catch Paul! Guess I need to make up a new hybrid drawing to cover the stock three terminal wiring. the first diagram I posted has the "GEN" generator terminal but the one from the manual hasn't got it. Go figure. I guess the engines came from Kohler with the S/G and Regulator mounted and the diagram only showed the wires that were part of the factory wiring.

953 nut 51,769 #27 Posted September 21, 2018 OK, Paul @pfrederi and Eric @ebinmaine, take a look at this drawing, it will be added to my electrical post. Share this post Link to post Share on other sites
ebinmaine 63,210 #28 Posted September 21, 2018 Looks good from what I'm learning but I'll ask Paul to take a peak. Separate but still related question. Will the terminals on the starter/generator, be marked?? I don't see any markings on the outside or near them. Share this post Link to post Share on other sites
pfrederi 17,147 #29 Posted September 21, 2018 There is usually a F or A stamped into the Genny housing. next to one terminal 2 Share this post Link to post Share on other sites

pfrederi 17,147 #33 Posted September 23, 2018 Regulator bases need to be grounded. i am not sure that zip ties will maintain an adequate sound. The saddle mount types screw to the Genny housing which is grounded. I think you may want to rig up some sort of permanent ground for the base of you flat mount regulator 2 Share this post Link to post Share on other sites

I think you may want to rig up some sort of permanent ground for the base of you flat mount regulator Nice catch on the zip ties Paul. What I did was wire brush a small patch on the casing of the generator and also on the feet of the regulator. Due to the fuel pump spewing gasoline all over the general vicinity I have not tested for voltage yet. Once I determine whether or not this regulator is putting out the appropriate voltage I'll get a couple of large metal hose clamps to wrap around the entire housing. 1 Share this post Link to post Share on other sites
Machineguy 876 #35 Posted September 23, 2018 @ebinmaine I don’t know if you’ve seen the Gorilla glue commercials? But if the zip tie comes loose that big gorilla might run up in the shop with some tape and give you quite the scare! Happened to me the other day when a bunjee cord fix of mine came loose! Scared me to death when that gorilla ran in my garage!! True Story! 3 Share this post Link to post Share on other sites

ebinmaine 63,210 #39 Posted September 23, 2018 @pfrederi and @953 nut She's up and running and starts on her own power and sounds great but is not charging. Can you give me a DVOM usable test that I can do to determine if it is the generator not putting out or the regulator not putting out? 1 Share this post Link to post Share on other sites
pfrederi 17,147 #40 Posted September 24, 2018 Ground the F terminal on the Genny to a KNOWN good Ground (or the battery - terminal) I do not trust zip ties. Anyway when you ground it you will here the engine slow a bit and the voltage should jump up to about 14. If so Genny is good and regulator is bad, not wired right or not grounded. If There is no increase in voltage then the charging field coil in the genny is probably bad. 1 Share this post Link to post Share on other sites

As a later development, I noticed a very serious whining noise coming from this generator so I'm going to have to swap another one on there anyway. Fairly sure this one has a bad bearing in the belt end. Share this post Link to post Share on other sites
pfrederi 17,147 #42 Posted September 24, 2018 I would still test it now. No point in messing with a bad bearing if the charging field coil is bad Share this post Link to post Share on other sites
