ty if i run a wire from switch to starter mower turns over fine but still no spark in the plugs
Right off the bat, I'll let you know I am not familar with Ex Mark equipment.
However, safety switches on the tractors I'm familar with will prevent the starter from cranking (for example, you're trying to start the machine while off the seat).
To me, if the starter was cranking, that eliminated the Safety Switches and PTO switch as possible causes. However, since you state you ran a wire from the switch to the starter, you may be bypassing the safety/pto switches. However, the engine should have started.
So, your initial problem was the starter not cranking...is that correct?
Which switch did you wire directly to the starter?
It will probably help if you respond with all the symptoms and everything you've done in sequence.
One sentence responses don't tell us much...I'm assuming, based upon your response (and abbreviations, lack of capitalization), that you're responding on a cell phone. Wait until you can respond on a PC or laptop so you can respond with more detail and as clearly as possible.
