Wheel horse 310-8 not starting.

[RITEK 25]

I was using this tractor and then the next day I start it up and nothing. In the past I've had to hot wire a turn off switch as I've deleted every safety switch on it. I've put a new coil and starter in it and I've verifyed they work. The shut off switch isn't the problem as I've disconnected it. Anyone know. Oil switch etc. Might not be working. The battery has plenty of juice.

 to the     Can you post the model and serial number of the tractor so we can find the correct wiring diagram?

 

Does the engine crank over OK ?       With the ignition switch in the run position, do you have 12V at the + coil post?

Yes I do. if I hot wire the positive to the starter is sparks at the post and does nothing.

Wheres the serial number located.

VIN plate should be around the seat somewhere, maybe just in front on the fender.  While you're at it, tell us about the engine, should be a Kohler, either K241 or Magnum.

[RITEK 25]

Magnum

[RITEK 25]

Mmm I still can't find the s/n

[RITEK 25]

Its this one

The picture is a K-241 not a Magnum.  Big difference in running down ignition problems. (no oil sentry on a K 241)  You said you ran a lead from batterY + to solenoid terminal sparked but no crank.  Have you tried a jumper from battery + direct to the starter motor terminal???

[RITEK 25]

I grounded the jumbox to the mount on the engine and touched it the the positive terminal and it spun over. And yes it a K12 is got the oil sensor

[pfrederi 18,558]

When you run the jumper wire to the big out terminal on the solenoid (The heavy lug with the wire that goes to the starter) you just get sparks but no crank.. You need to-inspect the wire from solenoid to starter.  If it is OK then maybe your solenoid has an internal short....

But the starter won't turn even if I take the batter and tap the starter with it

With a direct wire from battery to starter motor terminal no crank??? (I thought you said the starter motor was OK...)  Can you turn the engine over by hand???

[Ed Kennell 41,353]

The starter runs on the jumpbox but not on the battery.    Battery or battery ground is bad.

Why won’t my starter turn over from the key switch?

Lets take a logical step by step inspection of your starter problem.

Is your PTO in the ON position, a wheel horse will not start with the PTO on.

Have you had the battery load tested at an auto parts store?

Have you cleaned and tightened all electrical connections including grounds?

Are all fuses good and fuse holders cleaned?

If these have all been done, we can check components of the starting system as follows; don’t skip a step or you may miss the problem.

Be sure the transmission is in neutral and the parking brake is set.

Take a pair of automotive jumper cables and connect the black cable to your battery  "-" and a good clean spot on the engine. Now connect the other cable to the large post on the starter and touch the other end to the battery "+" terminal, does the starter turn over? If the starter turns over the battery and starter are good. If it didn't turn over try the same steps with the battery in your car/truck, if that cures the problem then the "good" battery wasn't so good.

Presuming the starter turned over move the jumper wire from the starter post to the other end of the wire going to the starter which is one of the large posts on the solenoid. If the starter turns over when the battery is touched by the jumper as before then that cable is good, if not you have found your problem.

Presuming the starter turned over move that jumper to the other terminal of the solenoid, connect the other end to the battery and use a small piece of wire to temporarily connect the battery "+" terminal to the small terminal on the solenoid, this should cause the solenoid to close and the starter to turn over. If not, the solenoid is probably the problem.

If this was successful remove the large jumper cable and use the small jumper wire to the small terminal of the solenoid, the solenoid should close and the starter turn over. If not the cable to the battery is the problem.

Presuming all of these have been successful remove the black jumper wire and repeat the small jumper to small terminal, if the starter turns over the ground is good.

If all of these components test good then remove your ignition switch, be sure the transmission is in neutral, parking brake on, clutch depressed and PTO off. Use a small jumper to connect the terminals that were connected to the “B” and “S” terminals of the ignition switch. If the starter turns over then the PTO switch and other safety switches are operating properly and your ignition switch may be bad.
