Voltage regulators

Anyone ever have to replace one? Do they go often? I have a Kholer 23 hp and battery is draining , not charging during use. I have checked all visible wiring , changed stater last year. Im wondering if there is a way to test the voltage regulator? Or if someone thinks it may be something else?... Thanks

From my Deere engineering days, the number one electrical warranty item was batteries. Followed by wire harness issues and then voltage regulators. So yes, they do go bad.

I'd start by checking the key off battery drain as well as load testing the battery, just to rule out there isn't a bad cell.

Thanks! I forgot to mention I did buy a new battery, guy at auto store said it was no good. And of course still having problems. Battery is at 12.50 running, and bit higher not running.

Not sure on the Kohler V/R specs but you should be somewhere 14.3- 14.6 at WOT.

Exactly where I was before this issue, im going to take the regulator off today and replace it with another to see if that is the problem. Im not sure of any other way to test it?..

Ran into this problem beginning of last grass season with my Kohler cv25. Tried regulator first voltage only increased approximately half a volt. Ended up being the stator and magnets on the flywheel. The magnets ended up "clumping" together.

My voltage was around 12.5 at wot. Mower would be fine for a day. I would carry fully charged batteries and swap out until I got a stator.

Third at one point had irregular charging problem when my flywheel key decided to sheer and the flywheel wasn't timed correctly.

I have now eliminated the voltage regulator, pulled one off of another kohler engine, and did the same thing. Put mine on his motor and it was at 14.50. I will be starting to take the top off this afternoon to get to the flywheel/stator. Of course it is not the easiest thing to get to. Thanks for the input!

Does your V/R have a voltage sense lead? If so, check it a multimeter to see if you are getting close to battery voltage. Kawasaki V/R's will shut down if the sense voltage drops to low.

It's easier than the pulling the flywheel/stator apart.
