Electrics are NOT my strong point....
With that in mind I took my Sears DMM over just to see if I could gain some more info.
The DMM is in "Auto Ranging" Mode and set on Ohms...
The readings were fluctuating a little, so I just wrote down the approximate value.
With the MH unplugged, and no genset attached or running, I took reading between the pins on the plug, and the pins and a ground point on the MH body... I hoped they might help..
I believe in the following pics the plug is Ground top pin. RH lower pin is 120v. LH lower pin is Neutral.
Between 120v pin and Neutral Pin was 6.5 M-Ohms.
Between Neutral pin and Ground pin about 13.5 M-Ohms
Between 120V pin and Ground pin 23.5 M-Ohms
Between Neutral pin and ground point on MH body 2.3M-Ohms
Between 120v pin and ground on MH body 11.9 M-Ohms.
Between Ground Pin and ground on MH body 3.0 Ohms.
