Hey folks, I have a Coventry Victor MW1 out of my 1951 Dippy. When I bought the boat the motor was out of it and because the wiring was in such bad condition the guy threw out all the wires from the ignition switch to the motor! So my dilemma is where do I wire the ignition switch? I turned the motor over to check for spark and it is sparking fine, but how do I wire ignition switch to kill the ignition so it doesnít run endlessly? I donít know where on the motor the wire should attach. If anyone had a picture of the ignition switch wires going to the magneto/ motor ,and could post it I would be forever in your debt! Maybe Miro knows?

Thanks in advance, Tom.

Ahhhh - those modern 1950's motors with electric start and magneto ignition.
As I recall, the ignition switch grounds the magneto primary so it stops the engine.
But as for the specific connections , well, that will take longer to find.
There are of course resources at the DisPro Owners Association who have the wiring info at hand. That's probably the fastest route to the answer

Ah thanks Miro, I have been through all the information the DisPro site has available online and no joy. I was hoping to be able to see another MW1 at an event this year but with everything cancelled due to the CV-19 that hasn't been possible. I'm sure it is ridiculously simple but without seeing I am baffled.

It's just a matter of grounding the mag to turn it off . The original keys closed the circuit when the key was turned counter clockwise some boats have had the key switches replaced and you have to turn it on to turn it off

Ah. Okay so if I attach a wire to the one terminal thatís on the top of the mag and ground it to the block that will kill the spark?! That makes sense. Thanks Mike!
