ignition switch

Just to clear this up I am saying a manufacturer cant build a system ( where uscg rules aply)that will shutoff the engine due to anything (for marine use). The kill switch can only be manually operated.

For ignition switches, if you have had a smoke event, and all is well now, you will probably have another when current demands go up. For high current contacts, after a sparking high resistance arcing event, usually caused by mechanical loosening holding the contacts, the contacts will exhibit higher contact resistance. So best to replace the switch.

If you can tighten the housing, and want to try and salvage the switch, for what little life it has left, you can try and clean the contacts with Caig Laboratories Deoxit D5 contact cleaner lubricant.

Id be trying to find out what the cause was , should never be that much current going through any ignition switch at any time , asking for trouble to just ignor it !!!.
if there is high draw use a better switch or fit a relay unit in the circut to take the higher loading .
Remember boats burn to the water line !!!!

No not true --the manula warns you of starting the engine by mistake and being dangerous.

Magnito!! how old are you.

Merc V6 engines have 2 power packs, one for each bank, some times they fail and one side of the engine keeps running . If you unplug the loom trying to stop the motor both banks light up.
