Hello all,
My 2003 toro commercial ZT mower with Kohler Command Pro 26 EFI burnt up the PTO clutch. I purchased a new clutch but before I engaged it I checked the running voltage at the battery. The voltage was immediatly 14.4v and slowly progressed up to 14.8v at which time I shut it down so as to not fry the ecu unit. Cleaned battery terminals and checked ground connections. Re-started it and the same results. Battery is 3 years old and starts the machine well. Checked battery voltage not running and found 12.4v which I assume is good. All cells were even with water. Decided to replace the regulator/rectifier with OEM Koher part and the voltage does exactly the same thing. Checked the stator AC votage and is normal at about 28v at mid throttle.
The service manual states that the voltage should not go over 14.2v.
I don't want to run the mower with this voltage condition for fear of destroying the new PTO clutch and the ECU.
Any thoughts or recommendations would be greatly appreciated. Don' know what else to do ...:confused2:
