I have a Troy-Built Bronco Riding Lawn Mower, Model # 13AV60KG011, SR.# IE308H20019. I can not get it to start, even make a noise 99 % of the time, it will try to start ever now and then. I check and see that there is no voltage to the started switch, don't know how the current is distributed to the solenoid or the safety switches. Does someone have a wiring diagram for the mower or where can I get one ? Thanks
