Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello my name is***** will do what i can to asset you.
To understand the mower only turns over with the brake saftey switch engaged. Did you remove the brake saftey switch? is that why you have it in the hand?
So when you barley push in the brake saftey switch you get spark to have the unit run??
If so the reason the engine doesnt spark is because one of the other saftey switches not working.. Some of the other switches is a seat switch.. If the switch is no good the mower dosnt know there is a operator.
ok let me pull up a wire diagram.
what saftey switches did you replace? brake, seat, pto, and the two switches at the arms..
here is a wire diagram.
i hope this helps..
ok.. Let me do some more checking in a service manual. i will get back to you
Sorry its been a busy day.. have you checked the relays?
if all is well then i will opt out cause i have checked what the service manual have said. wish u good luck..
Hello. Thank you for choosing Just Answer. My name is***** you are still in need of assistance, please let me know. I will be happy to work with you, to help figure out what is causing our problem.
Thanks for your reply. Can you give me just a minute or two to mark your wiring diagram?
please take a look at the wiring diagram below.
There is a part labeled Timer in the diagram. If this timer is not opening, when your seat is occupied, ground will originate at your Timer, via your Brown Wire, then through your Green Wire, and over to your Brake Switch.
Notice the White Jumper Wire. This wire goes directly from your brake switch, to the ignition coil on your engine. This is your kill wire. So, regardless if your Parking Brake is "on" or "off", your engine spark will be restricted if either your Seat Safety Switch, your Seat Safety Switch wiring connector, or your Timer has failed. Keep in mind that your kill circuit originates at your Seat Switch, via the Black Wire.
Process of elimination. You have already replaced your Seat Safety Switch, so we can assume that it is ok. This leaves your Seat Safety Switch wiring connector, and your Timer.
You and I can continue from here. Thanks again!
Thanks for this additional information. There is a Purple wire going into your timer. Check to see if your Purple wire has 12 volts when your ignition switch is in the on position.
Do you have a multimeter, or a way to check for continuity? If so, check to see if you have continuity between the (M) terminal, and your (G) terminal, on your ignition switch, with your ignition switch in on position. Remove the wiring connector from your ignition switch, when checking this. Check this after checking for voltage on your Purple wire.
