Hello All,
I've been having charging issues with my Toro which has a Kawasaki FR691V engine. I started out thinking it was a dead battery so I replaced it and everything was fine for a few cuts. Then it wouldn't start unless I boosted it. I did some testing with a volt meter and found when running at full throttle wasn't getting any additional voltage to the battery. I checked the DC side of the voltage regulator/rectifier and I do get battery voltage. When I check the two AC sides of the regulator/rectifier at full throttle I get 25v on one side and like 7v on the other side. I wasn't exactly sure what I should see from those, but I'm guessing they should both read in the 25-30v AC range. I figured this must mean it's the stator, but since it was easier and relatively cheap to replace I started with replacing the voltage regulator/rectifier. As I suspected I am getting the same results.
I have a few questions. What reading should I get from the AC side of the regulator/rectifier, and in your option does it sound like the issue is with the stator at this point? Are there any additional troubleshooting steps I can take to confirm? Are there any good tutorials or tear downs for this particular engine I can use? I have a good idea of how to replace it, it's just a matter of putting it all back together properly.
Thanks
