The jd 320 is still over charging. The Kawasaki is running great but it's still causing the battery to spit acid. I've been meaning with it all winter and am out if ideas. Here are the volts. Low idle high idle and running full throttle with the pto engaged.

Battery, starter, and regulator have all been changed with no effect.

Do you have a wiring diagram we can start from?

I don't know how the regulator works on those newer tractors. The only thing that comes to mind is the ground connection. If the connection that the regulator uses for a ground reference is compromised in some way it could possibly cause an over voltage. At this point a diagram would be a big help.

You sure that is overcharge?  Cars put out 14.5 volts up or down some to charge battery, would think the tractors would be about same?  You say the last 15 was from full throttle with pto on. Perhaps the tractor ups the voltage needed because of the electric pto?  Think you need a repair manual  and check some specs. Doesn't seem all that bad to me. Maybe the Batt is bad or main cables from it?

All I know for sure is that when the pto is engaged with the tractor running it causes battery acid to leak from the battery covers
