My 2010 Deere 2305 decided it doesn't want to stay running.

Customer Question

My 2010 John Deere 2305 decided it doesn't want to stay running. It was running when it shut itself off, and now will only run if I hold the key in the start position.

Have you checked you ignition switch to make sure it is send power out when you let it go back to the run position. It sounds like you might have a faulty ignition switch.

Customer: replied 1 year ago.
Black w/ red and Black w/wht maintain approx. same voltage as the battery, other two leads, blk and white w/black only have small amount of voltage when the key is turned to start
Expert:  Bradley Martin replied 1 year ago.

I would replace your ignition switch that should solve your problem

Customer: replied 1 year ago.
What makes you conclude that, should there be different readings from the switch than what I got?
Customer: replied 1 year ago.
What would cause the switch to just cut off the engine when it was already running?
Customer: replied 1 year ago.
Oil gage light and battery light on the control panel do not illuminate when the switch is turned ON either, they also stopped working properly with this issue. They will illuminate when the key is turned and held to start position.
Expert:  Bradley Martin replied 1 year ago.

check your battery connections make sure they are good and tight

Customer: replied 1 year ago.
They are. Brand new battery and both cables installed. Battery voltage is ~ 15.6V
Customer: replied 1 year ago.
Am I missing an inline fuse somewhere that could have caused this issue to multiple things? I checked main fuse and all four fuses in the "box", everything is good there.
Expert:  Bradley Martin replied 1 year ago.

Have you tried by passing the ignition switch and see if it will stay running?

Customer: replied 1 year ago.
I can't find a schematic for the switch, so I am not sure how to do that - meaning I am not sure which leads (wires) go where?
Expert:  Bradley Martin replied 1 year ago.

You should have a power coming in and the two wires with out power going out. Just connect your wires wires and to one of the wires that is not you cannot connect it to the starter wire otherwise the starter will stay engage only connect to the wire that does not engage the starter you may have to jump the starter out from the signal wire to the battery positive on the starter to make it run if it stays running I would assume your switch has failed

Expert:  Bradley Martin replied 1 year ago.

Any update?

Customer: replied 1 year ago.
Haven't been able to try yet. I am not sure I understand your directions without a wiring plan to let me know I am trying the right connections you are referring to.
Expert:  Bradley Martin replied 1 year ago.

You can also test the switch by ohming it out with a voltmeter do you have one?

Customer: replied 1 year ago.
I do. Would need to know setting for the meter and what to look for though.
Customer: replied 1 year ago.
I just received testing instructions from my local dealer service tech, I will give it a test as soon as I get home.
Customer: replied 1 year ago.
Switch test results are good. Everything checked out fine. Recommended check now?
Expert:  Bradley Martin replied 1 year ago.

Have you checked all fuses to make sure non are blown?

Customer: replied 1 year ago.
Primary 40a and all four in the "box" are good
Expert:  Bradley Martin replied 1 year ago.

Next check the connection to battery positive on the starter

Customer: replied 1 year ago.
Brand new battery and both brand new positive and ground cables. Voltage at the ignition switch is almost the same as the battery.
Expert:  Bradley Martin replied 1 year ago.

You initially said it will stay running when you hold it in start correct?

Customer: replied 1 year ago.
That is correct
Expert:  Bradley Martin replied 1 year ago.

i would check the fuel shut off solenoid next. See if it has power when key is on run position.

Customer: replied 1 year ago.
Ok. I was thinking I need to unbolt it and check the reaction of is coils.
Expert:  Bradley Martin replied 1 year ago.

Let me know what you find out

Customer: replied 1 year ago.
Ok
Expert:  Bradley Martin replied 1 year ago.

Any update today?

Customer: replied 1 year ago.
Did not get the chance to check it today

I have ordered a couple of diodes I plan on installing, one manages the voltage to the fuel solenoid. Might be Monday before I make any progress.
Expert:  Bradley Martin replied 1 year ago.

OK keep me updated please rate me when you get a chance.

Customer: replied 1 year ago.
Still waiting on part delivery.
Expert:  Bradley Martin replied 1 year ago.

Ok let me know how it goes

Customer: replied 1 year ago.
No parts yet
Expert:  Bradley Martin replied 1 year ago.

Ok let me know when you get the parts installed

Customer: replied 1 year ago.
Unfortunately, no part delivery yet
Expert:  Bradley Martin replied 1 year ago.
Ok no problem let me know when you get the parts on
Customer: replied 1 year ago.
Ok, so is swapped out the seat safety switch just in case, no change, still would not stay running. Then I replaced What I believe to be the v4 diode, controls current to fuel solenoid, no change, still won't stay running. So I disconnected the fuel second all together and it will stay running until I push in the linkage with my finger to cut of the supply. What next?
Customer: replied 1 year ago.
Disconnected the fuel solenoid, sorry, runs
Customer: replied 1 year ago.
Funny thing is the solenoid plunger only goes in when the tractor is in gear, it does nothing when in neutral. But the tractor will not start at all when in gear.
Expert:  Bradley Martin replied 1 year ago.

I would check your neutral switch it might need adjustment

Customer: replied 1 year ago.
how would I do that?
Expert:  Bradley Martin replied 1 year ago.

What I circled is the neutral switch make sure when the selector is in neutral that switch is pressed in if it is not adjust the gear selector linkage to where it presses that switch when it is in neutral

Expert:  Bradley Martin replied 1 year ago.

Any update today?

Customer: replied 1 year ago.
Haven't had a chance to check adjustment yet
Expert:  Bradley Martin replied 1 year ago.

Ok let me know how it goes.

Customer: replied 1 year ago.
the neutral switch adjustment seems to be fine. Cleaned out a bunch of dirt but it moves freely and only allows the engine to turn over when in neutral. Oil gage light and battery light on the control panel still do not illuminate when the key is just turned to ON (they used to come on), they will illuminate when the key is turned and held to start position. But engine will not stay running.
Expert:  Bradley Martin replied 1 year ago.

Have we already checked all fuses?

Customer: replied 1 year ago.
as far as I know. Unless there is something else taped up in the wiring harness.
Expert:  Bradley Martin replied 1 year ago.

Have we also checked the relays under the dash?
