Kill switch wiring help

[kaferboy]

Hi Folks, I bought a used 2014 Mercury 6hp 4 stroke outboard last year and am just getting round to checking it over and servicing it ready to actually be used. When I bought it the owner advised me that the kill switch had broken and he was just touching the two wire open ends to kill the engine. He was an old chap in his 70's and clearly had an 'old school' view on kill switches anyway, he had actually bought a new kill switch which I'm now looking to install. Don't know where he bought it, but I've seen similar on ebay. The original kill switch has only two wiring connections, the new kill switch has 4 spade connections, two of which are marked 'M' and two of which are marked 'C'. I'm guessing this is for two different kinds of system, a NO and a NC type circuit? Unfortunately I don't have a multimeter to check which is which, if this is indeed the case... Anybody know which way round the wires go?

I have had a good search and amazingly can't find what should be easily either googleable or findable on these forums!

Thanks

just a basic switch +ve white earth black it wont matter anyway since it just shorts out

if no meter use a battery and bulb to test switch

You need to use the M and M for it to stop pulling the cord out. The C and C will only stop with the chord in.

Excellent Davie, you've saved me from half an hour of messing about with wire strippers and spade connectors - many thanks!

just an update to this, it was actually the C C connections I needed to wire through, pull the cord out and bam engine stops. Just in case someone else searches for the same info. Thanks for the help folks
