OK
You need to remove the top cover of the genset.
Inside, under the black end cover, locate the control board, directly behind and below teh start switch.
Unplug the connector from the control board.
At the connector, locate the wires labeles P1-33 and P1-34.
Set your meter to ohms, and lightly ohm across these 2 wires.
What reading do you get?
