Yes. the diode is what keeps it from sending to much volt to and from the battery. if you jump it now if anything happens to the stat-tor it will go through the system not protected. i don't know a lot about them but was told by several shops to not bypass them.

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 318 wiring diagram I replaced an bg 316

Purple wire goes to the solenoid on starter.If you installed starter with single wire post all you have to do is mount a solenoid to the frame just in front of starter,existing batt/starter cable goes to one solenoid post,purchase a short red cable and install on other solenoid post and run it to the starter,plug purple wire into new solenoid and the way you go.

When I turn my john deere sabre off at the key the engine shuts down, however ten seconds later the fuse blows. Also brand new safety switches are killing engine when released. Suggestions?

Somewhere, probably in the ignition switch circuit there is a short circuit - otherwise the fuse would not blow. You'll need to take a test meter to each circuit in turn to isolate the circuit and then find the short. Be logical and patient!

John Deere 4230 new starter replace battery also and still will not start

Ignition switch, connections at switch, or small post on the starter solenoid, or wire broken between the two. Or possible bad "new starter solenoid". It's been a problem for other starters. May be a bad batch of solenoids. You may be alble to veryify the solinoid by a jumper from the positive battery terminal or cable to the small post solinoid terminal. If it activeates the starter, you know the solinoid and starter are ok and the problem is the wire or connection to the starter switch. If you had problems before, It may be a bad ignition switch and the internal starter switch. Did you test the old starter? you may not have needed to replace.

I have a two year old John Deere D-130 Lawn Tractor that Will turn over but will not start it seems to be an ignition problem of some sort (NO fire to spark plugs

These Briggs has two diode in the coil ground leads.

Here is few things that can cause this problem.
  • Short to ground in the wiring
  • Both diodes are shorted.
  • 12v is somehow being applied to the coil circuit shorting the diodes and destroying the coil packs.
  • Bad ignition switch keeping the coil packs grounded.
Step 1:
Start testing by first disconnecting both coil packs ground wires. If the engine now starts and runs you at least the coil packs are okay. If doesn't then both coil packs are bad. In this case don't reconnect until you can verify that 12v isn't being applied momentarily when operating the ignition switch. Proceed to step if the engine now starts.

Step 2:
Then reconnect the ground wires and disconnect the engine that feeds the coil packs and the fuel shut shut off solenoid and retest.
If the engine starts and runs. Then reconnect the harness to shut the engine down. This would mean that there either a bad ignition switch or a short in the wiring on the mower side and not in the engine side.
If it doesn't start start now after starting previously replace the diodes in the wiring harness paying attention to proper orientation of the diodes or replace the harness.

How to test a solenoid for a John Deere 115 Lawn Tractor with 42" deck?

John Deere Starter Solenoid Kit AM138497

First make sure the negative battery cable is making good contact on the frame or what ever part of the mower it is connected to. Make sure both battery cables are clean and not corroded and are tight. Then try to start the mower. If it works, fine. If not then you will bypass the solenoid and see if the starter turns the engine. To bypass the solenoid take a car jumper cable and connect one clamp to the terminal on the solenoid that goes to the battery ( see the diagrams in the links above) Turn the ignition switch to the on position. Take the other end of the same color of the jumper cable (say you'll use the red clamps) and touch the clamp to the other large terminal on the solenoid, which goes to the starter. If the starter turns the engine, then you know the starter is good and that the solenoid is bad. If the starter does not turn the engine then the starter is bad. make sure you DO NOT touch the jumper cable to the starter case or any other ground.

No panel lights

the solenoid for the ignition and starter has failed. Also remember the brake has to be applied to activate the starter system.

I have a John Deere LT115. When I turn the key, the lights come on, but not as much as a clicking sound.

Sounds like one of your safety switches might be engaged. Check to make sure that the PTO is off, the parking brake is set and you are in the seat. After that report further if still having issues. May also have a blown fuse or a broken/loose wire.

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
