A fully charged battery should read a minimum of 12.65, if it does not and connections and grounds are dirty then that's your problem. Start with a none fully charged battery.If you can bypass the solenoid and start it then the culprit is the solenoid. Good luck. donnyb60

OPERATOR PRESENCE SYSTEM
Be sure operator presence and interlock
systems are working properly, If your
tractor does not function as described,
repair the problem immediately.
• The engine should not start unless the
clutch/brake pedal is fully depressed
and attachement clutch control is in the
disengaged position.
• When the engine is running, any
attempt by the operator to leave the
seat without first setting the parking
brake should shut off the engine.
• When the engine is running and the
attachment clutch is engaged, any
attempt by the operator to leave the
seat should shut off the engine.
• The attachment clutch should never
operate unless the operator is in the
seat.

Check your seat switch and clutch switch wires be sure that the connection to each switch is making contact and the mechanism that activates the switch is actually activateing them in other words be sure the clutch is pushing the switch in and your seat switch is occupied and be sure all grounding wires a intack
especially from your battery negative to the frame.You also could have a neutral safety switch which requires your transmission to be in neural.
try these things and let us know how we can further help from more of your input.

SOURCE: Won't start, just clicks

I'm not familiar with this Toro Model, but that click sound probably is the starter solenoid engaging. Have you checked the wiring from the battery to the solenoid and from the solenoid to the starter? Also, check the ground connection on the mower frame.
You may have a bad starter motor. You can by-pass the solenoid by - placing a heavy gauge wire from the POSITIVE battery terminal directly to the STARTER terminal, where the heavy wire is attached. Be careful NOT to ground out the wire from the battery.
If the starter turns - it's a bad solenoid. If it does not turn - it probably is a bad starter motor.

you may hav a bad alt. problem with the mower dying when you engage the pto is most likley a bad sensor or wire unplugged on the seat sensor.the way it works is if the blades are turning and it dosent sense you being on the seat the mower shuts down.this has been standard on mowers for quite a few years now. it keeps the blades from cutting you up if you fall off the seat while mowing. as for charging i would try cleaning the battery connections and get the battery checked first.

ohm out the clutch......should be 2-4 ohms any less means the clutch has an internal short and will need to be replaced. also check the saftey interlock module, however the modle numbers u gave do not come up, relays checked ok? how did u test them?
