Starter generator overcharges--fixed

[jimking67]

Hello--Recently I posted a problem with the S/G overcharging on a CC 127. I ended up taking both my S/Gs and all 3 V/Rs to a different auto electric rebuild facility for evaluation. The problem was------- the V/R.!!! Not defective, but incompatible with a S/G. The "cheapie" V/Rs are electronic, although they are physically identical to the original units.The electronic units will not properly regulate the voltage/current on a S/G, which only has ONE field coil for charging. Thus, the high (full -fielded) charging rate.
They will work fine on a generator only charging system, even though on the Internet they are advertised as working on generators and S/G s. The correct V/R for 12 volt S/G application on Cub Cadets is Delco Remy mechanical V/R # 231-12004 (Made in USA).

The "cheapie" V/Rs are electronic,

We were under the impression that these V/R's were CC or suitable replacements. NOTHING was mentioned about electronic V/R's.

I never saw a "cheap" electronic voltage regulator. What were the part numbers from Tractor supply? I have converted replacement Delco 10si regulators to work on a SG. The one field coil should not cause the regulator to full field. If you can, take a photo of the regulators with the tops removed. I would be interested in what is in those regulators.

Jim,
Did you replace it with a Delco Remy V/R and it's good now? I've been to tsc and haven't found the correct one for our cubs so I've never bought one. They were all 6 volt jobs at my TSC. Anyway thank you for posting your answer, we appreciate you letting us know the end result. I am doing a "renew" on one of my originals and purchased an old Delco VR on purpose. If you look at the internals on them there's a reason they last 40 plus years as opposed to the Chinesium junk ones they build now. Thanks again for the information

I'm with Roland (although quite the stiff reply) that if you were using an electronic one that would have been really good info to have as I'm not sure there's a solid state V/R out there that has worked on our stuff yet with S/G's

To my knowledge there is only one V/R that is a solid state.... and it IS NOT CHEAP! I find it tough to believe that it is a solid state and cheap.

Yes, that info would have been good to know. I do remember asking if it was the correct regulator and you said it was. If you don't give full and accurate information it is tough to help you, and very frustrating on our end.

My point exactly. Some of us chased out tails trying to help and repeatedly asked about parts and wiring and weren't given the correct information.
