In which case my first reply is still valid, the PTO switch will have several safety circuits running through it and they are very difficult for people with no idea about what they are doing or basic DC electronics to bypass properly.
As you might have already guessed I do not have much time for people disabling safety switches, regardless of the fact I do not believe in them. The best safety switch is between your ears.
Apart from seats on ZTR's which were too sensitative there is however little reason to dissable switches unless the person has a serious dissability , as none of them prevent quick & efficient use of the mower.
We have had this discussion on here 100 times before and just like gun regulations it is very polar with both sides fairly well entrenched in their ideas.
To be frank, I would rather see mowers made safe to use with guards and not any of the switches bar the seat switch or some other dead man device that kills the machine stone dead the instant there is no one in the seat or the operator has a seizure / heart attack etc.
If we came across people on a daily basis missing fingers , hands , toes etc from careless use of their mowers then it would be reinforced in our minds that these things are very very dangerous tools.
But unfortunately all of the safety gear installed makes it next to impossible to injure yourself so people use their mowers in a totally brain dead fashion, in a dangerous manner in dangerous situations then sue the factory when they succeed in doing damage.
And I am not trying to be preachy here .
I have a customer with Lupis so she can hot hold a bail for any length of time.
The solution is a pin that holds the bail closed tied to a string around her wrist so if she falls over the mower stops , not bypassing the bail all together.
So if you have the wiring diagram just follow the kill wire back from the coil to where ever it grounds, and there will be a lot of places where this can happen.
If necessary print it out a couple of times, pinch a coloured pencil from one of the kids and trace over the kill wires for each situation or use different coloured wires for PTO on & PTO off
IF there is no pin out for the PTO switch then pull it out and measure across the contacts.
It is a simple sliding contact switch that connects left to right and generally all of the middle row will be tied together.
