L35 = Eveready Bunnie

[Damifino]

First off, "Happy New Year to All".

I was talking on phone with my Brother yesterday, he has a L35 that has been used lightly, it also has been stored outside.

The problem he is having is that he can put key in ignition, turn and start right up, the problem is when trying to shut down, the key will not shut down.

Here's what I have told him to do so far. Spray wd40 in ignition switch and work with key several cycles, this however has not solved the problem.

I will be going over to his house this weekend, would like to be armed with any diagnostic procedures to attempt, if it's a bad ignition switch, then will tell him to replace.

If when turning the ignition switch off, is there some sort of solenoid that cuts fuel to engine, I have not done a face to face with the L35 and wanted to get some input of some of the more experienced.

Thanks for help in this matter.

My experience is with an L3650 that had the same problem (twice). There is a kill solinoid that cuts of the flow of diesel to the engine. I, too, thought it was the ignition switch so now I have an extra one lying around. Your brother's problem may be the ignition switch but it is not likely since the tractor starts when using it.

Take off the side engine panel to see the injectors. There should be a cylinder about the size of a tomato paste can with a 6" to 8" rod sticking out of it and attached to an apparatus in the fuel line feeding the injectors. It should be easy to find.

The can (solenoid) will have a single electrical wire coming out of it. You can test the hot side of the wire by using a test light or meter to ground. Turning off the tractor should light the lamp or show 12V for a few seconds then go dead. If you get nothing to the wire then the problem is most likely the timed relay that supplies the wire.

Then try hooking the battery directly to the solenoid. It should retract and pull the lever thus activating the fuel shut off valve.

Also, to make sure you have the right apparatus, try manually pulling the rod toward the solenoid while the tractor is running to experience the fuel shut off feature. Hold it there for a few seconds to keep the engine from stumbling back to life.

Both the relay and the solenoid are about $80+ each.

The relay and solenoid are very sensitive to water. Getting the engine wet is death - washing it with a power washer is certain death. I know.

gwdixon,

That's exactly the info I was looking for, way to test as you have provided info on and the real life experience with the ignition switch.

Thanks
