Exmark lazer Z 23 Kohler charging issue

I have gone thru 3 batteries this spring. The mower runs fine for a bit but voltage dissipates over time til the mower no longer will start. I put a new Exide 350 CCA in today it started right up. Reved up the RPM on the mower and Put a meter on the battery there is no voltage surge at all. This leads me to believe I have a Regulator or alternator issue? I am looking for diagnostic advice Please. I was having some clutch issues last season where PTO would sporadically not engage- could this be related?.

Another issue may be unrelated? the motor does not consistently respond to the throttle- particularly when I trying to throttle down. Throttle wires move appropriately on the carb but the RPM sometimes do not reduce.

My Air went out on the house this week and I am trying not to have to see the dealer if possible$$$

Thanks
Chazmo

I just had the regulator go bad on mine. The 3 prong plastic plug was melted. I think the terminals get dirty over the years and build up resistance, thus heating up and frying it.

Your symptoms are similar.

Check your fuses..
Unplug the 3 wire plug on the regulator..clean the connections and plug back in..
make sure the regulator has a good ground...either a wire or a strap...clean connections.
