Kawi FH451V Electric Problem

I have a Gravely 34Z with 350 hours on it. It has the 15 HP Kawi. A while back the battery went dead and the mower would not start. I went and bought a new battery and it ran for a while, but the battery just slowly went dead again. It must be the thing that keeps the battery charged.

What should I look for? Thanks for any help.

First, Check for battery voltage to the single plug connector on the voltage regulator with the key in the run position. If you have no voltage to the regulator check for a blown fuse or faulty ignition switch.

If you have voltage to the regulator perform the "Unregulated stator" test as below, If the stator checks out as being good you can move to the regulator test to just to be sure the regulator is faulty.
