I have a wizard riding mower, that won't start, starter will not engage, have replaced with a new starter, a new key switch, a new battery, and have checked all safety points for alignment. Would like to know if there is anything else I can do. Thanke in advance for any help... wizer

Check the solenoid. That's fairly common at going bad. That's the only thing in the link I can think of other than a bad wire
