Hi vint_mow That switch is obviously factory set up, I couldn't see how to get that metal cover off so I could trace any of the wires. That diagram you have put up is good info if somebody has to dig into it. I might have to dig into the kill switch part in there today because this motor had spark 2 days ago because I had it running and yesterday it had no spark. Would have been so much better if they had used different colours on the wires so you could trace them
I'm not sure, but I've been told the risk with having a starter button on the handlebars is that I could accidentally engage the starter while the engine is running. But as I will be disconnecting the battery after the engine fires up, this is not a problem. I use to carry a battery on the machine at one time, but found it too difficult to mount and the vibration killed the batteries in a short time. So now I just wheel the battery around separately on a dolly to start the machine with some Anderson cables.
The following is posted for information purposes only!
For applications where the battery is permanently connected, I can only suggest a timed relay to shut the starter motor off after the engine fires, or adding an extra switch to turn the starter on and off. Something like this might do the job perfectly. I can only find these switches for sale in America and they are pricey. Could probably get one for a few bucks on a site like AliExpress, that is if it ever arrives.
The Blue and Black wires on START are not needed and only two wires not three needed for the on/off switch.
There seem to be two different models (NO and NC) for the off/on, but I've been told the wiring can be changed simply by removing a rubber seal at the bottom of the switches.

So you accidentally push the starter button while the motor is running, big deal, you have never accidentally gone to start your car while the motor is running? Stop overthinking it just gets you more confused.
I edited my post around the same time as you posted.
Well it's on the handlebars Norm and as a mate warned me, it could be easy to brush up against a tree branch or accidentally bump it myself. But as I don't have the battery hooked up permanently, this isn't a problem anyway. I was just posting up the warning in case someone else tries to replicate my method and they have a battery hooked up permanently. Better to be safe than sorry. Starter motors and geared flywheels are expensive.
Believe it or not, I did one time hit the starter in my car when the engine was running. No harm was done on that occasion, but the grating sound was pretty dreadful and definitely not a good thing to do.
Off road bikes have starters on the handelbars and you never hear of them having problems trashing around in the bush and having things bump the starter button.
Well most times okay, but mowing around lots of bushes and trees with overhanging branches is a bit different. I guess that is why they use key switches located down on the engine instead of buttons up on the handlebars.
But as I said, doesn't concern me anyway because the battery is not hooked up permanently.
Not sure what you are doing there vint_mow when you say the battery is not hooked up permanently, do you connect it up every time you need to start it?
Yes Norm, I hook it up to a wheel around battery through an Anderson cable to start.
This is all part of my Rover Heavy Duty walk behind slasher renovation. I have tried to mount a battery on this thing a few times but really there is nowhere to put it. I would like to see how the Deutscher Heavy Duty Walk behind slashers manage to incorporate a battery mount. I guess if I ever make up a heavy duty steel belt guard to cover the top, I might be able to mount a small battery on top of this. One day I have plans to incorporate the battery, but for now have put it in the "too hard" basket.
Putting the switch up on the handlebars is more a safety feature than anything else. If ever I have inexperienced people using this machine, there is a risk they could start it down on the engine with their feet underneath the thing or hands in the way of the belts. Putting everything up on the handlebars will reduce that risk.
Hi vint_mow, this is where I have mounted the battery on a couple of Deutschers. I could have used smaller motorbike batteries which would have made it easier but this is what I ended up doing
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
