What would happen if the engine start button is pressed when the car is running???
I have installed the buttons to my dash and put the engine start under the clocks in the centre with other buttons to the left and right.
I have just had a thought..... What would happen should the start button get pressed when I am driving along (accidentally pressed or pressed by
passenger)?? If it will engage the starter then thats going to cause problems. Im thinking it might be best to install an additional switch to the
right of the steering wheel that must be on for the start button to work.
Any thoughts?
Cheers!

It would make a crunching sound as the starter would try to engage, wouldnt hurt much once every so often, but I wouldnt make a hobby of it. I plan on
wiring via a relay that would disconnect the starter circuit when the engine is running.

wire it via a relay off the oil pressure
I'd love to give my imaginary friend a great big hug,
but this jacket makes it impossible.

My bike loom has 3 relays on it already (modified by MK) for ignition, crank and clutch. Would this already have something that disconnects the
starter circuit when its running? Im not sure how it worked when the bike was running, I never tried pressing the start button when it was already
running.

I ran a relay off the ignition light feed, works a treat.

If you are running a GSX R engine, then no damage will occurr if you were to accidently press the start button. The Starter gear on the engine is a
one way clutch. Assuming the engine is running at 1000 rpm or faster, then the crankshaft is turning faster than the starter one way clutch so the
starter will not be able to drive the crank. The usual speed for cranking is around 400RPM, which is 600 RPM slower than the crank is turning even at
tickover. Promise you no damage will occur.
Please bear in mind that this is a BEC and the starter motors work completely differently to a bendix type starter. The BEC type gears are permanently
meshed.

If it can't be fixed with a hammer then its probably an electrical problem.

Better to do it off the alternator light as oil pressure may not drop straight away, if you stall etc
