Help John Deere died

Mtnryder · Dec 19, 2019

Just quit while operating. The power comes on when I turn the key to on but the battery light stays off and the starter doesn't engage. I have fuel and oil and a new battery and all the fuses are OK.

Have you checked your battery contacts?

Check to make sure the sensor under the seat didn稚 come unplugged

Check that your gear shift is in neutral. Check the pto switch. This could be any of the safety interlocks ...

I have inadvertently bumped some of the levers with "neutral safety" switches and it cause some concerns till I verify all the levers are in proper safe position to allow start...

As a troubleshooting solution there should be a 12 volts of voltage off start lead from ignition switch (going several safety interlocks ) going to solenoid on starter when key is in start position.... IF you do not get the 12 volts to start terminal on solenoid you might have a bad interlock switch "somewhere" on tractor... Probably need wiring diagram to trace out "starting" circuit...

if it was running and quit, I would guess an issue with the Fuel shutoff solenoid, when you turn the key on do you hear the "click" of the solenoid
pulling in to turn the fuel flow on? I have a PDF of the Deere tech manual you're welcome to, has lots of troubleshooting in it. Shoot me your email if wanted.

You turn on the key and the battery light does not illuminate? It is supposed to be on any time the key is on and the engine is not running. It could be the bulb and unrelated to your problem. Or it could be another symptom of your problem. Several things can prevent your starter from engaging but a safety switch or wiring to the switch could kill your tractor while working as well as preventing it from starting again. As a first guess I'll say check the seat switch and any wiring going to it including the fuse. You could have a pinched wire if the switch is working properly or perhaps a mouse had a snack.

Also check your fuses.

New battery

Mtnryder · May 18, 2020

In the OP I did that.

Mtnryder · May 18, 2020

It is running the battery down. Getting no charge from the alternator obviously, since it did it twice. I checked the belt, it is OK

Mtnryder · May 18, 2020

Please. The alternator is not working or something. hdmtnryder@icloud.com

Take the alternator off and get it tested.

If you have a volt meter put the leads on the battery posts with the engine running. The volt meter should read 13.8 to 14.5 volts depending on the charge of the battery.

That will tell me if it's charging, why didn't I think of that? I'm starting to think it is the regulator. If it was the fusible link it wouldn't start with the key right?

it should start with a bad fusible link, that only fuses the output of the alternator, with a fully charged battery, it should still start.. and then stop when the battery is discharged.. after running a while.. do you get lights?. you could have a bad battery cable, or a blown large fuse somewhere else.. have you tried a jumper cable from the + battery terminal to the small(solenoid) wire on the starter to see if it cranks over??..

Yeah, it runs until the new battery dies, and then when I charge it it runs another 3-4 hours before dying. I get lights, and I checked all the fuses. So I should replace the link first? It is the easiest fix. LOL
