Custom Wiring - Kill switch

[Noodleman]

Evening all,

I hope somebody can help me out. I have nearly finished the re-wiring of my engine. Im oing for stop/start buttons on the dash, as the boat sits on a trailer at home when not in use.

I have a mariner 60, old 1976 (i think).

The only issue i have rightnow, is that I am unable to stop my engine once it is running.

I believe to stop the engine, i need to ground "something".

now, im thinking i just take a +12v from the battery, and ground it, however... doing this would cause a battery short, right?

So, what do i need to ground, in order to stop the engine?

Any advice would be welcomed. many thanks in advance

Alec.

To turn your engine off you should have a black/white wire coming out of the ignition box just run a wire to a switch that grounds the system to turn it off.

alas, im afraid the colour of wires inside the motor i have mean nothing, as it was re-wired / bodged by the previous owner, so i am having to work them all out.

The wire that should be grounded to turn the engine off, do you happent to know what it will connect to?

Somebody recomended to me that it was the ground cable from the ignition coils, but i want to do my homework before trying things to make sure i get it correct first time.

The motor is an electric start by the way incase that makes a difference.

Many thanks

Alec.

The end of the box should have 3 wires, 2 go to the coils the 3rd is the kill wire

ok, I think i can work out what needs doing.

My motor is a little different to that..

There is 1 wire going to the coils (2 wires total as there are 2 coils). This is the live.

Then, there is the lead to the plugs, and a third cable, which is the ground from the coils.

These are currently grounded to the engine, i assume breaking this connection will cause the coils to stop sparking, and stop the engine.

If thats the case, I will whack in a switch to the circuit.
