Check your safety interlock systemget a wire jumper and test each switch and please dont leave them bypassed if you do find the problem. We have a company here that bypassed all the switches on a lazer z. The machine flipped over and because the switches were bypassed, the machine never shut down and when the guy tried to pull himself out from under the machine he reached up ,grabbed the deck to pull himself up and lost all four fingers along with a broken leg and cracked ribs.

Follow the clutch wires down toward the motor/clutch area. There will be a connector down at the deck area, either on top of the deck or below it. Make sure they are the wires for the electric clutch. The motor IS NOT running. Seperate the electrical connector, and using a multimeter, check for OHMS, or continuity, turning the button on and off. That will tell you if the switch is working. With the connector still disconnected, and the motor running, check the switch for 12 vdc using the multimeter. That will tell you the wiring at the switch is passing/not passing the necessary 12 vdc to run the clutch. After all of this, the only thing left would be the clutch. Perhaps it is "frozen", and needs to be adjusted. Let us know what you find out so far, and we can go from there. JIM.
