Hello, I want to implement an arduino with my motorbike, and one of the things i need to do whit it is to shut down the engine.
The bike has a kill-switch for shutting down the engine. The kill switch, when pushed connects one wire(coming from ecu) to bike ground.. I measured the voltage between this wire and ground, and it is up to 8V when the engine is in high rpm. I then used a ammeter to shorten the wire and ground with the engine almost at full rpm, and the current was 60mA, and the engine shut down of course..
So i need to build some kind of hardware to make this possible, i think that using a reley is not an option because i need to shut it very fast and precize, and this is a kind of dirt bike so there is a lot of vibrations and shocks, and i dont think that this is too good for a reley..
Is there any way to do this?
thanks for your time!
