if it starts with the brake on, the brake switch is working. there is a spring rod unter the seat that pushes the seat switch. Unplug this switch and use a jumper wire to bypass it. if it works that is your problem. you can adjust the travel of the rod by readjusting the nuts on it. the easiest way is to remove it because they afre on the bottom and difficult to get to.
there are safety switches on each steering arm, the seat, the brake, and a seat delay module behind where the throttle panel is. all of these can be tested by jumping them, or with an ohm meter. your manual will tell you if they are normally open or normally closed switches.
