Ok, it's making sense now Marty! The voltage regulator for the IH Cub Cadet Original, and the following models 70, and 100, all use the same four terminal voltage regulators (IH-121577-C1). The "gen" terminal is on one side of the vr, while the field, battery, and load terminals are all on the opposite side.
Voltage regulator #IH 545130-R92 is another four terminal vr. This time, the "G" terminal stands for GND, or ground. This terminal is also on one side of the vr by it's self. Field, GEN, and BAT terminals are all on the opposite side of the GND terminal.
Ok, so now voltage regulator #IH-545130-R93 is a three terminal vr, having the fiels, gen., and battery terminals all in a row on one side of the vr. .
I don't know the reason my 125 has the R92 vr. on it, but I was told the 125 started and ran fine. I don't recall a charging issue with the battery or not. My model 72 has the same vr. and harness as my model 71 did. The only difference between the 71 and 72 notes in Charlies FAQ's, is on the model 71, the gray lead is running from the magnetic switch to the battery terminal on the voltage regulator. While, on the model 72, diagram shown with a charge indicator, the gray conductor is coming from the (-) negative terminal of the charge indicator to the battery terminal on the voltage regulator. I also have a spare model 100 harness complete, which shows IH-121577-C1 as being correct for it's respected model.
So, when I began taking pictures and videos of my 125 before tear-down, I noted that green custom wire coming off the GND terminal on the voltage regulator going straight to the starter generator
support bracket mount cap screw.
My plan is to inspect the three terminal voltage regulator, and install it in my 125. This is because I don't know if a 125 had the R92 voltage regulator, and if it did, was the ground wire included into the wire harness/loom? My 125 harness does not include a ground wire for such purpose.
Again, my "goal" with my 125, was to get it as BACK as close as possible, to "correct police" condition as I can!
Side note, I seen an officer of the police department today, he has a motorist stopped on his Harley Davidson motor cycle! The bike was very well taken care of, and just reminded me of the old days, when the officers would be sitting behind the bill-board, and come screaming out from hiding after the motorist speeding! Thought it was neat to see today.
Going to continue patience, and care with the remaining harness and voltage regulator installment. from this point, I can then focus on the k301, and carb! Finish up cleaning the grill and hood, and hopefully get a spark from this great, IH Cub Cadet model 125 garden tractor! Takes some time to completely go through one of these garden tractors with care, that's for sure!
Jason W, Charlie is an amazing help! He knows just what we need, and that too is a huge help with these garden tractors!
Well, what about Charlie? He pulled out the 100 with trencher. Wonder what the next couple months will have in store for it?
Jim, again, very nice find,...1650 with loader!!
