Can you turn the engine over by hand? Make sure the engine isn't seized or jammed somehow. If you can turn engine over by hand, check if there is a p.c. board in the wiring , (probably under the dash if there Is) if you have checked everything else and there is a p.c. board then that will be problem. I had a same problem last week with an atco GT30H , checked starter motor, solenoid, battery and switches and was a faulty p.c.board

It requires the following safety states.

Seat occupied
Parking Brake depressed/locked
Mower disengaged (PTO off)
If automatic trans, shifter in center slot.

Is the click you here the solenoid or a safety relay activating.

Check voltage scross the solenoid coil. It should read battery voltage when key is turned to start. If its stays at zero, safety relay is opening or there's an open wire or miswire.

If the solenoid coil energizes, then either the starter positive is not properly connected or starter to ground via engine block (mounting bolt).

percussive maintenance my friend. Try banging on the solenoid and starter with a hammer while in the start position. Also, if you have a voltmeter, you can see where voltage is getting to and that will help you as well.

SOURCE: john deere stx 38 with black deck, will not do

I see this problem not as an electrical but a seize problem. Since I can't be there to inspect I am relying on your discription of the problem. I would go first to the place of the problem. If this solenoid goes up to disengage and down to engage ,or the opposite, this is most likely your problem area. It may be seized in the disengaged position therefore not allowing the blades to get spinning. Disconnect the belt and try to turn unit by hand, if tight or completely stuck use penetrating oil on pulley shaft.If shaft loosens up and blades engage this was the problem. Is there a grease fitting anywhere in the area?I hope this at least gets you started in the right direction. GOOD LUCK.

SOURCE: I have a John Deere LX280 that won't start.

The fuel solenoid is 12 VDC. You can power it directly with 12V from the battery with the connector disconnected. It is powered from terminal A1 of the Key Switch with the switch ON. Before powering it up do a resistance check of the coil on the solenoid. It should read 40 Ohms or less.
The seat switch only provides a ground for the ignition. If the starter solenoid is engaging you should also have power to the fuel solenoid. Check for 12VDC on the engine harness for the solenoid with the Key ON. If you have 12VDC the solenoid is bad.

I am answering this post now as it appeared AFTER I had replied to another post. I note your post is 7 days old. Had I seen it 7 days ago I would have answered at that time. Sorry for the belated response.

SOURCE: John deere Z225 riding mower

measure with a valt meter and see what your voltage is at the battery . now measure what you have for volts at the soleoid. then check to see if you are getting 12 volts to the single peg on your soleoid, usually a whitwe wire. If your not getting voltage to this wire you probably have a safety switch problem. If you are getting voltage here check to make sure you are getting voltage at the starter motor. If your getting voltage there you may have a bad ground at the starter motor or the whole motor may need to be grounded to the frame.

My John Deere 0-turn want grant with key


Unfortunately yes. From what i understand , power is going into the solenoid but not coming out, resulting in the starter not activating. Good news though, new solenoids are pretty cheap and not that difficult to replace. Included is a tutorial on a similar mower .

Why won't it start?


When I turn the key nothing happens.
There are several elements that go into cranking (turning over) the engine.
  1. Battery
  2. Fuse
  3. Key Switch (and wiring)
  4. Starter Solenoid and wires
  5. Starter motor
To begin with check the fuse. It's a 20amp car style fuse located under the hood near the battery.

If the fuse does not fix the problem let's move on to the battery. The quickest way to make your initial check of the entire starting system and particularly the battery is to get a jump. Yep, get some jumper cables and jump the mower off your car. Turn the key and try to start it in the normal fashion(normal meaning YOU in the seat, PTO off, BRAKE pressed all the way down). If it starts cool! It is likely a bad battery.
  • Charge the battery for a few hours, on a charger.
  • Then perform a voltage measurement of the battery.
  • Switch a volt meter to DC Volts and clip it to the battery. It should read between 12-13 volts. If not the battery is suspect. If it is 12-13 volts see if it will crank, but continue to watch the volts. If they drop below 10ish volts, the battery may have a bad cell.

Now let's check the starting system while bypassing all the safety switches and wiring. How? You can perform this test simply by jumping the starter solenoid. Hold a wrench or fat screwdriver across the two large posts of the starter solenoid. This bypasses the key switch and all safety devices and directly drives the starter. Your starter will crank if the battery and starter are good, the wires and connections are good, and the engine is not locked up. Don't crank it for more than a couple seconds. You just want to verify the battery and the starter are both in good shape. (The engine will crank but not start during this test as long as the key is off, or if the safety switches or wiring are damaged, or if the safety switches are in the no start/run positions.)

If the starter cranks try one more test. Run a small jumper wire from the positive post of the battery to the little terminal on the solenoid. You may have to take the small wire off the positive terminal of the starter solenoid, in order to do this. When you apply this current from the battery to the positive terminal it should make the solenoid activate and the starter crank. This test bypasses the key switch and shows you the starter system is working. You could do this test first; if it works you do not need to do the basic jump test.

If these tests cause the engine to crank, but it will not crank with the key, then you know you have a problem somewhere in your starter wiring, safety switch system, fuse, or in your Key Switch. Of course you did check the battery terminals for tight, clean connections, right?

Most modern riding mowers have the following 4 safety switches:
  • Seat switch
  • PTO switch
  • Reverse switch (RIS) and Reverse Relay (RIO)
  • Brake/Clutch switch
If you need detailed instruction for testing your wiring and safety system, I will need your complete machine info.
  • Make
  • Model
  • Year
  • Engine Model
  • Transmission Model
  • Deck Size.

On a John Deere (100 series) the starting current flows through the following items in this order:
  1. Battery to Fuse then to the Key Switch.
  2. With key switch in the start position, the current flows from the Key Switch to PTO.
  3. With PTO off, current flows from the PTO to Brake/Clutch Switch
  4. With Brake/Clutch Pedal all the way down, the current flows through the switch to the starter solenoid.
  5. If the Starter Solenoid is in good shape, the solenoid connects the battery to the Starter and the engine cranks. Cranking does not mean running; it just means the engine turns over. Running is dependent on many other systems.
Those components are all part of the cranking/starting system. They can prevent the Starter Motor from cranking when you turn the Key Switch. You can trace the voltage with a multi-meter. Connect the black lead to ground and look for 12 volts at each successive switch. If the voltage disappears at one particular step, there is your suspect.

Electrical elements that are NOT part of the starting system:
The RIO is the Reverse Implement Option. It is a switch that latches and stays latched under certain conditions. It is activated by the RIS. The RIS is the Reverse Implement Switch. It activates the RIO.These switches are called slightly different names by different manufacturer, but they all do the same thing. These two separate components work to allow the blades to cut while you are backing up (without killing the engine). They have nothing to do with the starting system.

The Seat and the RIO (the reverse latch not the button) switches are tied into the engine kill system. They provide a ground path for grounding the Coil. This same system controls the fuel shut off valve beneath the carburetor. The Seat and RIO can keep the engine from running but they will not prevent the Starter Motor from cranking. Therefore, if you turn the key and nothing happens, the problem has nothing to do with the Seat and Reverse switches.

Note: With the Key in the RUN position, power flows from the Key Switch to the Hour Meter, then to the RIO latch relay (not the RIS button), then to the fuel shut off solenoid. If you do not hear the Fuel Shut off Solenoid clicking on and off when you turn the Key Switch from off to run, there may be a problem in this circuit; including a possible problem in the Hour Meter. Of course none of this affects the cranking circuit. Your engine will still crank, it just won't start and run.

My 2014 Craftsman 247.20374 T1600 wont start it just clicks. Briggs 19hp, single cylinder. 46" deck.


The source of the clicking sound is likely the starter solenoid. Typical solutions are:
- Charge the battery (it has too low of voltage).
- Remove corrosion build-up on battery terminals, solenoid wire terminals and ground wires.
- Replace solenoid (it won't engage and only clicks).

Why does my LA105 john deere lawn tractor only click when i turn key?


The click you hear is the starter solenoid. If the starter doesn't engage, it is suspect.

The starter solenoid may be stuck in the on-position. To check this, on the starter, remove the small wire connected to the solenoid coil terminal. If the starter still runs, the solenoid is stuck on. If rapping it with a hammer doesn't stop it, the contactor pin is welded to the motor contacts.

There is a switch under the seat. Just to test and not to run, you can take a jumper cable and go around the switch. If you find this works, go get a new swtich. It is very important for safety...Good luck...Lee
