It has to be closed to make the circuit.

i thought kill switches were open, and closing shorts out the ignition? at least thats how it was on my lawnmower...

Hi
looking at our earlier blade haynes manual when the switch breaks the circuit one of the feeds (or earths) to the coils and ECU is broken. It looks
like run position is when the switch completes the circuit but I could be wrong..

Closed to run on on the main bolt on terminals.
On the smaller connectors you have a two, one is closed ignition off (this grounds the engine side to earth via a resistor to stop the alternator
running the engine), other closed on run goes off towards the ignition/efi feeds so powers the engine only. Do not also feed the lights etc through
this or it will burn out.
Regards Mark

I think Mark slightly got the wrong end of the log and is talking about an FIA kill switch as used in racing cars etc, which has one big set of
terminals for cutting the main +ve lead, then two smaller pairs to cut electrics etc.
Anyway, from my notes on starting the 919, the stop switch needs to be closed to fire.
