Seat Safety Switch Location

I have a 1992 310-8. Yesterday the engine started dying when I engaged the PTO (mowing) . I finished mower with my pusher. Don't want to  do that again!

 

Anyway I am trying to troubleshoot and understand I can 'jump' the seat safety switch to diagnose (only). Where is the switch or the plug located? What size wire do I need? If the seat switch is ok, can I do the same with the PTO switch? 

 

BTW, the belt moves the mower by hand when the mower is off

Here is your wiring. Each circuit has its own diagram.

The weight of the operator in the seat is what activates the switch. If it is the push button type the button should be on the rear fender pan under the seat so the seat can contact it. The wire feeding the switch shows as being white. It should have power in it with the ignition key in the RUN position. Motor does not need to be running. Closing the switch should pass power to the other wire on the seat switch which goes to a relay probably located below the battery. You should hear or feel the relay close when the seat switch is activated.

Not a heavy load so a wire as small as 18 gauge would serve as a jumper to connect the two seat wires.

 

Let us know what you find.

For diagnosing purposes, separate seat switch from the rest of the wiring harness by taking apart the inline connector under the seat.  Put a paperclip into the two female terminals.  If the problem goes away  you know it is a seat switch.  Some seat switches use a pushbutton, others use switches that clip into the seat.  The latter are not so reliable.

Thanks for the help.  Wiring De-Mysticification is right!!! It is fixed now.

 

Troubleshooting led to jumping seat switch and that wasn't the issue. I  followed wiring diagram and it indicated that a wire from the PTO to the ignition switch. My ignition switch was pulled out a little from the wiring harness. It was a simple loose connection. Of course it took me five hours to find it, but that's another story. 

 

 

Fixed. Done. On to the next thing.

 

Thanks

      Won't start
      By OHLB
      Newbie here. 310-8 won't start. Battery is dated 10/19. Did crank a couple times but started losing ummph. Should I replace it or attempt to charge it? Can't tell if the battery is frozen. Never knew until today that batteries could freeze and that it's dangerous to charge a frozen battery. It's been single digits with wind chill the last couple weeks here.

      310-8 Speed & Drive Belt Change
      By Rob R
      Soo couple of years back did a pulley change on the tranny from 6 inch to 4.5 and used a 1/2 X 79 belt to make it work and it worked fairly well but wanted to get back to a 5/8 drive belt so went to a 5/8 x 81 inch belt and added a second flat Idler pulley. I simply cannot believe how smooth and sharp it shifts and drives now!  The added flat Idler was 2 3/4" with a 5/8ths bore used and existing hole on the side shroud and just opened it up a bit. I use to slip a bit on steep hill with the 79" slips no more, the belt drives and the clutch is  LOT smoother and in the right pedal area.... Will see how it holds up cut 3/4 of an acre of grass yesterday NO issues.

      busted tie rod, heavy duty replacements?
      By Ifixoldjunk
      So I was out mowing the other day with my 310-8 and somehow snagged my wheel in a hole in the yard. Anyways I pretty much destroyed my ball joints. I've since replaced the tie rod with junkyard parts but I was wondering if anyone's found a heavy duty aftermarket replacement for the tie rod assembly.
       
      Like would generic adjustable go-kart tie rods do the trick?

      Custom front weight bracket.
      By Ifixoldjunk
      so I spent a few hours today welding up a custom front weight bracket for my 310-8. It has two and a half inches of ground clearance with a generic 12 inch weight bolted on. 
       
      so the question is, how well do y’all think the 300 series front axle will hold the weight? It’s only 50lbs so it’s lighter than the snowblower it has to hold up in winter so I don’t think I’ll have any problems. And I really don’t intend on using it constantly.
