Do you have the regulator connected to the battery? To any load? The regulator will likely put out a voltage that is a bit above normal charging voltag with no load. I expect the voltage from the regulator to be in the 14V+ range, somewhere near 14.5, and 15 without a load sounds normal.
If you measure V on either of the two 'outboard' leads on the regulator, it should be in the mid- to high 20V range.
I believe the regulator body must be grounded to the engine for it to function properly and you may get some pretty wilde readings if it is not grounded.

Thanks for the reply Tom. The regulator is connected to the battery and the battery is charging. My biggest worry is plugging in a new PTO and damaging it. But I was hoping once the PTO is connected the actual voltage going to it would be correct. The voltage regulator states 14.5 volts +- .5 V but Im getting 15.2 V at the battery and PTO plug, I may be overcomplicating this but just want to do it right.

I have not connected a new PTO to it yet in fear of damaging it so I'm measuring 15.2 V at the plug that would go into the clutch.

 

15.2 is on the high end but normal . the voltage will drop when the PTO is engaged , the PTO is just an electro magnet higher voltage = more pull force . its a " dumb " part.

 

I'm wondering how low voltage affected the bearing in the clutch. I know that clutch bolt torque is critical for bearing life. Extremetorque has info on that. I use 50-55 ft lbs

 

I doubt the PTO failure is related to low voltage .

 

Just curious, what style of electric pto clutch was replace, and with what.
Ogura, Warner, model number . . . , I ask because the Warner style clutch is directional
specific and will fail if installed with the wrong orientation.
Thanks,
