The reason I used this battery is because it is the same as the one in his rideon so he can swap them if needed. His rideon is a 16hp so it needs a bigger battery.
So I pulled apart the switch module on the Chonda GX-200 clone last night. I am surprised at how basic the wiring is. Just four connectors, two for on/off and two for making the connection to the starter motor. The off position is exactly the same as the old style "kill switch" - just grounds out the coil. So it is nothing fancy. I see no reason why I should run into problems by leaving the key turned on and running basic bypasses for on/off and starter. If anyone can see any problems I am potentially missing, please post. I am already aware of the possible risk of bumping a starter button while the engine is running, but I came across a cheap timer delay relay online which could easily be put in the starter circuit to disconnect the starter motor a short while after starting.
Hi vimt_mow, not sure about the earth from the starter haven;t seen any like that before, as the starter motor is bolted to the motor it is earthed that way As long as your batt negative is connected to the mower frame or to a bolt somewhere on the motor that is all you need. Also with the solonoid earth you can use one of the bolts holding the solonoid to the body
