Looks like the 850 I once owned. Yours looks pretty complete except "valve cover" and gas tank. They are tough great running machines. Let us know when your light up some light bulbs! Here is an excellent site for Delcos.

Good luck!

Some history on the company itself: https://www.farmcollector.com/farm-shows/delco-light-plant-zmlz13janzbea

Your plant looks like an early 850 with the hard to find battery charging meter. In use, you could set the meter, somewhat like a timer, so the plant would shut down when the batteries were charged. A shame that it's so weathered, but the plant should run without it in the circuit. You can use three 12 volt riding mower batteries wired in series. This will produce 36 volts instead of 32, but the plant won't know or care.

Pull the cover off the generator itself first and see if mice have done any damage, which can be repaired with either shrink tubing or liquid insulation.......a brush on product available at Ace Hardware stores among others. If the windings are oily, they can be cleaned with careful use of spray brake cleaner. Go easy....you don't want to dissolve the rubber insulation! Follow with spray on laquer insulation to seal them and keep everything dry in the future.

The only major headache might be the small coil INSIDE the large coil on the front of the panel. It is wound to around 300 ohms with 37 gauge magnet wire so it's prone to break if old. I wound a new coil on a piece of cardboard tubing until it read 340 ohms on my meter, then installed it. Worked like a champ.

Model T valves with oversize stems can be fitted and I believe ordinary Maytag 2" piston rings will fit also. Be aware that these plants never had what could be called "stunning" compression. If you can spin the flywheel by hand against compression and have it bounce back a bit, it should run as is. The main bearings are rollers, so usually in good shape unless water in the crank case has caused rust. Even then they can usually be cleaned up enough for ordinary purposes. These old plants were built to be TOUGH!

thanks guys, I rescued this one from a scrap drive and I'm trying to figure out what I need before I get to work on it. It was outside so the meter and solenoid are pretty beat up. I need valve cover, gas tank, points cover, coil and anything on the board, thanks Mike
