A continuity meter across the terminals of the switches should confirm if they change when switched. As poly says convention on most petrol engines is that with the kill cord pulled the switch is closed shorting the spark circuit to earth. Simply disconnecting that switch wire should have the effect of stopping the short.
I was also confused by the added kill switch, I was told that a previous owner fitted it as he didn't like the standard kill cord set up
I believe the mercury switch can be set to "run" without using the cord, hence why the guy changed it
I will disconnect the earth of both tiller and cord kill switches and see if I have any success.... Also test switches if I can borrow a continuity tester
Thanks for the advice shinyshoe
