I was wondering if anyone would know how to check to see if a Kohler Magnum 20 is charging.

I am not sure if the wiring is hooked up right for sure or not.

With a voltmeter across the battery and running at mid-throttle you should see 13.8-14.7V DC. If not there, measure between the two outer wires on the voltage regulator and you should see around 28V AC.

Here is a link to the Svc. Manual. Check pg. 8.9
