DIY engine stop/start, with clutch + throttle switch restart

second attempt is my Hyundai Santamo. The kill switch is now right hand operation and cuts the injection. And it is self holding. Way better, for engine braking, as deep down as you want. a little slower at restart. i countered this witch a hypersensible throttle switch.

the simple kill switch alone makes about 90% of the trick in my case. the self restart is barely used and avoidable. at the end of the last video is shown a stop without a restart.

i used the build in injection relais to kill the engine. thats the first step.

second is restart, the technik is simple. a circuit:
12v batterie - throttel - clutch - service switch - relais coil - 12v alternator

messure out the thin pin at the alternator, witch goes from 0v to 12v when the engine is running. the 0v are basicaly ground. so the relais is operating when the engine is not turning and all switchen are closed. this relais leads 12v to the starter. done.
