Glort, thanks for the explanation. That does sound like I hit the jackpot! That is exactly what I am hoping for with this. I have a remote cabin on my farm in Tennessee that I intend to make completely off-grid.

Now, I just have to figure out how to wire it! The previous owner hooked a battery to the starter and pulled out the solenoid (he said it needed to be replaced because it is stuck). The starter spun just fine and the engine started right up. It sputtered black smoke at first then ran fine for a few mins till he shut it down.

While it was running, he hooked up a grinder to show me that it worked. So, I know it's putting out 110 at least. I have to get a battery and diesel tank this weekend to be able to start it and test again.

Thanks again for all replies!

I went out and grabbed a good multimeter today. I plan to start figuring the wiring out soon. It does have 2 car battery type terminals coming from the generator box. I'll try to pin each wire out and label it to see where they go. (It appears the factory labels are still on some of the wires).

Hopefully this will get me started on rewiring it correctly, or at least enable me to ask intelligent questions!

Here are some pics of the generator box. You can see the battery terminals coming out of the side of the box

Hi Lastlaugh, good on you for posting the photos. Please photograph every aspect of every step, not for our benefit but for your own, in three months from now, when you have found spares, you will have a visual record of how it all goes back together.

I am a little concerned that a single 12 volt battery will not have enough grunt to start an ST2. My ST2 requires 24 volts (two batteries) to get it fired up. You could probably overcome this by fitting two solenoids with a timer to drop the decompression levers (start one cylinder and use that to start the second). It may be that the starter built in to your generator head is a more powerful unit and all you will need is a high output 12 volt battery.

Keep us posted.

Bob

Yes sir, the starter that is attached will work off a regular 12v car battery. (That's what the previos owner connected the battery to) You are correct tho on the 24 volt part. Every SOM ST2 I have found online (mostly youtube) have had 2 batteries wired in series, but no starter. I think mine may have been added also.

One thing I have noticed tho is that mine is missing the box that sits near the decompression levers. I'm not sure what it is called or where I could find a replacement. Would you care to show pictures of how yours is wired up?

I'm gonna need the air cleaner/ filter and fuel tank also.

Hi Lastlaugh, you are sadly missing more than you think. Please see the photos and drawing attached.

Don`t panic, most of this stuff can be replaced with modern equivalents at a reasonable price. I will be talking to Rob at Old Timer Engines in the near future and I will ask him if he has any second hand SOM components in stock. You could also contact Gary at DES he sometimes scraps old equipment and keeps the good bits.
