F235 Starting problem

[vietvetharry]

Tractor Ernie or anyone familiar with the F235. I've been having intermittent starting problems, but now won't fire at all.

When I turn the key right to 1st stop, I get a click, then when I turn key to start, the engine turns over, but it won't fire.

I noticed before when it was intermittent, that along with the click I also heard a series of approx. 3 sounds and when that happened and I turned to start it fired right up.

I checked all the wiring I could locate and checked the fuses. The far left 5amp fuse was blown. I replaced it. I had the battery checked and was advised it had a bad cell. I replaced it today.

It still clicks once, but won't fire.

I attached a picture of a control I can't identify. Can you tell me what it controls and could it be bad & causing this problem? The voltage reg is a sealed unit. Can it cause this kind of problem?

From my questions I know you can tell I'm no mechanic. Can someone point me in the right directions.

IF all the ground and positive contacts are clean and corrosion free then the symptoms sound as though your starter solenoid has intermittent contact internally. May be dirty or bad. A reliable re-builder should be able to diagnose and make the repairs reasonably (compared to a new starter).

Thanks Mark, now can you tell this newbie where to find the starter solenoid .

It will be a small cylinder connected to the starter.

Here is a link to what one looks like Electrical System: Starter Solenoid

Thanks, I found it.

Question: If the motor is turning over, but not firing, would a faulty solenoid cause that?

Hi Harry,

The F series tractors have a fuel shutoff switch on the right side, between the fuel filter and the engine block

It's the little motor that makes a winding noise when you turn the key on & off.

Do you still hear the winding noise?
If not, MAYBE your fuel shutoff switch went to heaven.

The first click that you hear is the glow plug timer switch.

Please let us know if the shutoff switch still works.

If it does'nt I know HOYE tractor has one on the shelf, if I dont

Not a starter solenoid . A fuel shut off solenoid yes. Sounds like problem lies in the fuel shut off circuit.

Thanks Ernie, You're up early, since it's only 8am on the East Coast.

I think I found it. Does it have a little lever on the side? No, I don't hear it attempting to operate. The whirling sound you mention was probably what I was hearing after the chick.

I just ordered a starter solenoid from Hoye. I'll try to cancel that and switch it to a fuel solenoid if you think that is what the problem is.

You've always been a life saver for many of us F series owners.

I've think Ernie has you on the correct track. When you first said all you heard was a click, that didn't seem correct to me unless there was more than once design.

From the sound I hear, I've always assumed there was a mechanical shutoff operated via an electric motor. Motor sound is heard for 1-2 sec.

Have always asssumed this to be the fuel shutoff. Located aft of the injection pump and below of the fuel filter. Since I've not had any problems, I've not paid that much attention to where this valve is located. This just looks like the can of a motor.

Thanks Mickey, what did we do before digital cameras!?

Could you imagine trying to explain to this "dimwit" what it looked like and where to find it.
