I just tried the "remote start" feature.
The generator has a pigtail with a 4-pin connector on it. That connects to an optional control panel that would be installed in the cab of the RV. I have the troubleshooting and installation manuals, which show the color codes of the wires. I tried jumpering the "crank" wire to the "ground" wire as the illustration shows that the start switch does that. It DIDN'T make the starter go. I did hear a small "click" inside the generator. Sounded like a relay.
Perhaps all four wires have to be connected to the remote panel, or it won't work right? The four wires are crank, kill, ground, and "running" (which runs a light indicating the generator is on)
Here's the generator, mostly reassembled.
On the left, you can see the four-pin connector for the remote start panel. The orange hose is the LP fuel input.
I propped the generator up on a pair of 2x4s. The generator would normally be mounting on rails in an RV, and sort of hang down from them. On the bottom here, you can see the oil filter and the flywheel/cooling fan. The muffler also mounts under here.
I also dug up the piece of sheet metal with the ID plate on it. If you want specs on the genny, here they are.
These generators were originally made about 20 miles from my house. Kinda cool to have one of that brand for my project.
Here's a little video for you as well.
