I am not familiar with the JD 175 but knowing that JD has lots of safety devices on their equipment, I would check them. Did you just get it and was it running when you got it. Did you get it from a dealer? If so I would be on the phone as soon as possible with him. Sorry ... I realize this was not much help but I like to look for the simple stuff first on a machine that's new to me.

Might6 have to be sitting on the seat to start it. Some have pressure cut out switches that if you aren't sitting no ignition....

 

[KENSFM]

If the starter motor runs it probably is not a safety switch problem.

Some machines use independent safety switches that operate independently of the starter circuit and just kill the magneto/coil, but will allow cranking. This is done to make trouble shooting for a dead engine simplified. If it cranks and won't start, start looking for a switch that is grounding out the ignition.

Ok took the engine cover off so I could look at the coil and heres what I found.

I have contiunity from the ground wire of the coil to a ground.

The coil ohms out at ~18K ohms from the ground to the sparkplug wire. Is this right or wrong?

I do NOT get contiunity threw the coil.Right or wrong?

And 100 percent sure there is no spark.

Bad coil or no?has to be right?Im confused
Thanks

I don't know a thing about you particular rider. I do know I had a Murray that had a safety switch under the seat. It wouldn't crank unless you were sitting in the seat.

I had the bright idea of cutting the wires to the safety switch and wiring them together. It would crank then but had no fire to the plug, thus wouldn't start. I rewired the safety switch and used it until I got my tractor.

 

[Junkman]

Take a jumper wire and clip it on the positive side of the ignition coil and put the other end on the positive side of the battery. Crank engine and if it starts, there is a break in the wire from the ignition switch to the coil. If it doesn't then you either have a bad coil or the points are burned out. Report back after you do this and we can go from there. What is the brand of engine and if necessary, I can send you to the correct engine group for further assistance.

 

[cavaselis]

Im not sure which one is the ignition coil, If you are talking about the coil/mangeto that supplies spark there is no positive termilnal to that just ground and the ground at the coil has coniunity.

In almost every case where I have had bad ignition on a small engine, it has been the points or condenser. You may have to pull the flywheel to get to them. They would have been the first things I would have replaced.

[BillyP]

The positive terminal would be the wire going from the coil/magneto to the condenser.

 

[slowrev]

The Kawasaki will have electronic ignition, do NOT cross 12 volts over on it or you will Fry it if not already bad. Sorry but that is all I know about it. Get a small engine repair manual that covers it , is my recommendation.

 

[cavaselis]

Ok i called around to some JD dealers and we have come up with either the coil or most likely the Ignition trigger there both 50 bucks each Im goona replace the trigger this week and I will post back.Thanks for the help.

Polish the iron part of the coil that sets near the flywheel and the iron inserts in the edge of the flywheel that pass next to the coil with some emery cloth or sand paper before you buy any parts. One of my hands fixed his lawnmower that way today. I haven't bought a lawnmower in years, I pick 'em up off of trash piles and fix 'em and this is a very common reason for no spark.

 

[cavaselis]

Well, I got it running, It was the ign trigger, 55 bucks from JD.
Thanks again I wish I could figure out how to post a pic on here.

 

[cavaselis]

I figured it out check out the tractor.I have ~260 bucks in it.
