Missing circuit interrupter - MEP-831A

I bought this generator a couple months ago and finally got around to trying to fire it up. After attaching batteries, adding new oil and fuel, she fired up on the first try; however she wasn't putting out power.
A closer look and the Circuit Interrupter light is missing (see pics) and the "overload short circuit" light is illuminated.
After reading through several posts on this unit and trying to troubleshoot the issue I started with trying to eliminate any moisture in the inverter. I let it run for 20 minutes, killed it then let it sit for a couple hours while I worked on something else, came back started it back up and it solved the problem - if everything worked out this well....

With that said, I'm still missing the light. Does anyone know if this is a standard part? Can someone take a pic of the back side of the control panel and give me a better idea of what I need and how to wire it.
Thanks in advance.

Why don't you download the TM's for this gen set from the TM section? Then look up the part. Then use the NSN given in the TM, to get one?

When you get the part, the wire schematic in the TM will show you how to properly connect it.

The short circuit light could have come on because one of the wires that should be attached to the light socket was touching the frame/door.

Thanks for the helpful comment.

Let me try this again... I was trying to get out of the door yesterday and forgot to attach the photos.
I key word searched the TM I have (9-6115-639-13&P) for "circuit interrupter", but there are no hits that show a wiring diagram. I was hoping to tap some existing knowledge here before spending too much time on my own. Thanks in advance for the help.

What you are showing as missing there is the indicator light. It is DS6 on page 585 of the manual.

You should find on the back of the control panel, and next to most components mounted anyplace on the set, a discription. Like DS6, or K1. It helps you find the items on the schematic much easyer. If you do not find the markings, then someone did sloppy work at reset. All sets came from the factory marked.

The light is easy. One wire is ground. One wire is 24volts, for the press to test function. The last wire goes to K1, (I think). In any case, the wires are numbered. Easy street. The 24 volt wire is probably the reason you got a short circuit light. It touched the control panel door.
