Hi, I have a John deere S92 rear engine rider that my neighbor gave me. I was having problems with the interlock switches but i got the thing started. The next day i went to start it and nothing happened. No clik... nothing. I recharged the battery. And i bypassed the solenoid with jmper cables to from the battery to the starter. It didn't work.
So my question is is it possible to install a pull starter to an engine that was built for an electrical starter? Model 252707,
Also I want to see if the solenoid worked but there are so many wires on it. So you point out what each terminal on it is from.
Finally, i was wondering if you could explain how a killswitch/ stop switch works.
Thanks very much. Vincent
Answer -
I do not know of any way to install a pull starter on that engine. Those engines used a stub on top of the crankshaft to accomadate a starter clutch.
You could check the crankshaft. If the flywheel is held on by a large nut then it can't be converted. However, I've seen some of those engines that used a bolt instead of a flywheel nut. These engines can be fitted with an adapter for a pull start.
The shut-off switch. When you turn the key off, the switch grounds the ignition coil stopping the spark. The engine shut-off terminal is located on the engine block usually near the throttle cable assembly...you should see one wire, from the key switch, connected to this terminal and the other end of the wire is connected to the engine coil.
As for the starter, remove the starter cover and make sure the starter gear is not binding on the flywheel ring gear. I rarely find bad starters.
How many little wires do you have on the solenoid?
Let me know.

Hey , thanx for making that killswitch thing clear.
The gears for the starter and flywheel are fine. But they're not even touching.
AlsoFor the wires on the solenoid:
There are 2 top terminals, 2 lower terminals, the bottom is a metal surface, and there is small terminal behind the main thing.
2 Top Terminals-
1. has a thick red wire coming from the + battery, and a small red wire going to i don know where(maybe key)
2. has a thick red wire going to starter
2 Lower Terminals-
1. has nothing coming to it
2.has 2 black wires stuck together at terminal
Metal Bottom Surface-
I am thinking that this is where the solnoid get it's - , because elsewhere the wire from negative terminal of the battery is connected to the chassis/block/frame.
Small Terminal-
just a blue wire going to transmission, and then to key.
(i think its just a safety switch).
Thanks a lot , let me know what these mean. I hate electrics right now. Im 15 and they still haven't taught the stuff in school.

AnswerWOW!! That's an interesting set-up on the solenoid. I haven't worked on or even seen a S92 in many years.
Good call on the safety switch from the tranmission.
Since you tried to bypass the solenoid with the jumper cables and it didn't work you may have a bad battery or a bad ground. Bad grounds are very hard to trouble-shoot.
Did you try using the jumper cables straight from the battery?
I normally connect the positive jumper cable to the starter termial first. Leave the ground, black jumper cable end loose. Connect the other end of the jumper cables to the battery. Make sure the positive cable connected to the starter is not grounded to the starter case housing. So, you should now have one end of the jumper cables connected to the battery and the other end positive is to the starter terminal with the black ground lead hanging freely. After double checking the connections, you can now connect the loose/free negative cable to a good, unpainted metal part on the mower. The starter should turn.
Do you have a digital or analog multimeter?
How about a 12 volt DC test light?
If you do not have either one then I would suggest the test light. They are cheap and work well for what you need.
Let me know how you jumper cable test goes. If it doesn't turn the starter then I'd try another battery. A vehicle battery will work, just don't leave the cable connected very long...less than a few seconds.
Be careful not to reverse the cable ends and watch out for sparks!
Let me know what happens.
