I am in Kentucky - 4 hours ahead of you.
I work 2 day jobs, and help on Just Answer in the evenings.
Although I can not be online 24/7, I am online almost every day.
If you are getting 0 volts output, here is what I need you to do. It is not easy, but it can be done.
Remove the 12-pin VR connector again.
Locate the wires marked J2-9 and J2-10 (or P2-9 and P2-10).
Make up 2 jumper wires, with a 5A fuse installed inline on one of them.
Set your meter to ACV, and connect it to the output leads of the genset.
Working on the right hand side of the plug (that leads back inside the genset), insert the jumper with the fuse into the back of the plug at J2-9 (or P2-9).
Connect the other end of the jumper to either a 12V battery, or the battery terminal of the starter solenoid.
Insert the other jumper into the back of the plug at J2-10 (or P2-10).
While pressing the start button, connect the other end of the second jumper to the negative terminal of your battery, or to a good engine ground if you used the starter solenoid.
Be careful and only hold the insulated part of the wire – you may get a small shock.
How much voltage registers when you jump 12V to it like that?
