I replaced my battery on my JD 318 last week. A voltage test showed that the battery was discharging 12.5 volts, but only the same 12.5 volts when the machine is running at high throttle. A voltage check on the alternator (stator?) wires that lead to the voltage regulator (VR) was 50v AC at high throttle. A voltage check on the voltage regulator clip that connects to a third wire was ~3 v DC, which tells me that the VR might be bad although I just replaced it two years ago. Does this sound like a VR problem or is there a problem with the stator since I"m getting 50 v AC, which appears high? I was told the stator should put out ~30-36 v.
