Hi Bert ,
I am using a multi meter as per utube tuition
When I connect my meter to the new regulator/diode (2 white wires) it tells me I am getting 28 volts AC on tick over and 36 volt AC at full power from the new stator to the regulator
But then it shows I'm only getting 4.02 DC output from the regulator/diode battery charge wire
I have grounded the new regulator to the engine mounting bolt as per Kohler spec
Not sure if this helps as I'm not that well up on engine electrics
Regards John
