1989 john deere 420 will it start part 1

[@SF-fm7ov]

Quick method: Jump start the solenoid with a screwdriver. Once I get an engine cranking, I pour a 1/2 ounce of gas in the carb. If it runs for a few seconds, I then provide fuel from a quart size gas tank that I suspend in the air above the carb. If the engine sounds good, I will spend some money fixing other things. I might also do a compression test. FYI, after I changed the transmission filter and trans fluid on my 420, I noticed a small drip. Mine has a large hose from the bottom of the hydraulic pump to the bottom of the differential that was leaking. I wish I had changed that before putting in the new fluid.

Many key switches have the contacts marked with letters. S is the wire to the starter solenoid.

That piece of the box says Cummins because onan is a Cummins product. Just makes the parts more expensive
