Cub Cadet 125 Voltage Regulator Questions

[ol'George]

Suggestion:
Install both "new" regulators on your 124.
That will confirm if the 125 has a problem OR the new regs are poor quality/faulty
And post the results!!

That is a reasonable suggestion but it will have to wait awhile. The 124 is blown, busted rod. I used to have another 125 that's gone. As for the 124, there are no local machine shops except one possible who will do the block but not the crank. Just put it on back burner till I have time. I doubt the 125 has issues as it works fine with the 124 reg. I even switch generators for the test just to be sure. Both gens fine .

Try changing the amp gauge from the 124, BTDT

The saga has a few more chapters.

The regulator I got from the board sponsor worked for about 3 minutes then pegged the ammeter full charge. I tapped on it and it then went full discharge. I took the cover off and looked, but I can't see anything burned, bent or otherwise amiss. I'm not going to fault the sponsor because I've bought other things from them and have never had any problems. I think the manufacturer made a bum regulator.

I didn't want to wait to get another regulator shipped in from the internet so I went to the local Cub Cadet Dealer. They didn't have one, but were willing to try to get one for me. Again, I didn't want to wait, so I headed to the local Starter/Alternator service shop to see if they had one. The owner sold me one that was listed as being for that application. I took it home but no luck, it didn't work either.

The shop owner had given me his card and said to call him if I had problems, so I called him. He said to bring it right over, along with the generator and he would figure out a way to get it to work. When I got there, he told me that he had contacted the manufacturer and was told that they had some regulators that were assembled wrong and I got one. He put the generator on his test rig along with a different regulator. That worked, at least on the test bench.

I took the generator, along with yet another regulator home and put them back on the tractor. I wired them up and started the engine, lo and behold, it worked! I checked charging volts and amps and they were right where I would expect from a working charging system. I drove it around the yard for awhile and it kept working, so I decided to declare victory.

It took 3 different regulators, but I finally found one that worked.
I hope I don't need another one anytime soon.

Thank you for the "the rest of the story"
Sadly, faulty right out of the box, seems to be the norm lately post covid.
I've seen it myself with auto parts,
even from reputable suppliers I've used for decades.
I hope it gets better soon, it hurts everyone, and we all pay the price of higher costs as well as down time.

Yep...faulty right out of the box! It was what I trying to convey about the two faulty regulators in a previous post. I wasn't asking advice, however, it is appreciated. Thank you!
