Q:

how do I check my rider mower model # 917.276843 switch, selenoid, starter, safety switch? 917.276843

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the starting issue you're having with the tractor. I know how frustrating that is.

First, make sure the engagement lever is down or the PTO button is pushed in and the brake pedal is fully depressed or the tractor will not attempt to turn over. If you have already done this, I recommend checking the fuse. The fuse is located behind the dash. If the fuse is good, you have a wiring or switch problem. The easiest way to pin point the problem is with a volt meter. If you do not have a meter, you can purchase one relatively cheap.

Turn the meter to check dc volts, and then hold the black lead to the black negative battery terminal for all of the voltage checks. Place the red lead on the positive terminal of the battery. The reading should be 12 volts. If you have a 12 volt reading, move the red lead to the B terminal of the ignition switch or the red wire. Your reading should be 12 volts. If you have 12 volts, have someone sit on the tractor and hold the brake pedal while turning the key for the rest of the checks. While they have the key turned to the start position, move the red lead to the white wire on the clutch/brake safety switch. The reading should always be 12 volts. Then move to the attachment PTO safety switch. If you lose the 12 volts, the problem is between the last check you had the voltage and where you lost the voltage. If you have 12 volts all the way to the white wire on the solenoid, the solenoid or the starter is defective.

To determine starter or solenoid, short the two large posts on the solenoid together with a screwdriver. There should be a spark it is normal. Once shorted the starter should run. If the key is turned to Start, the tractor should fire up.

This very likely could be: a defective battery or loose connections, the fuse, a shorted safety switch, or a wire that’s shorting or grounding out.

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.
