Hi , I can not get my Prowler 650 to even try to start. It had gotten to where you had to cross the terminals on the solenoid to get it to turn over but then once it started it wouldn't turn off. I had to disconnect the wires to cut it off. Now it does nothing. I replaced the starter switch, solenoid and CDI box and still nothing will not even try to turn over. What's left to replace?
