Toro Z5030 model 74373

Changed the battery, now, when the blade switch is engaged it stops the engine. After checking,electrically, the ignition switch,PTO switch,seat switch,kill relay, both park brake switches,and FlyBack diode, all passed electrically.

Another "change" just happened...pull the PTO switch.......... blades do not engage at all.

And, all I did is swap batteries.............Now....Ain't That Weird???

Hook your meter up to the Orange wire at the ignition switch. It should have 12v on it in the run position. This wire goes to seat which then become Yellow. This operates the kill relay which also controls the ground for the PTO clutch. If the relay does not operate then the PTO clutch will not operate. Also if the Relay is not operating it will kill the engine. This because when PTO is pulled the circuit through the controls is disabled, and it relies on the seat switch circuit to keep the relay engaged.
