Re: 1970 Merc 110 9.8 wiring HELP!!

The salmon wire and other kill switch, stop button, go into the stator, coil, mounted on the stator plate. They creat the DC elecrtic that makes the motor run. When the kill switch is shorted to ground, the block, it stops the flow of electricy and causes the motor to stop running. The diagram shows a laynard kill switch that is the man overboard kill switch on some motors so equipeted. That wire is the black wire comming out of the stator, coil, on the motor.

Pretty sure they run grounded and un ground when you hit the kill switch on these motors. This system is not hard to wire up at all, the diagram is spot on. You can't just throw any kill switch on these motors, it's a grounded system, read the cdi troubleshooting steps, they say to ground the salmon wire off the kill switch and check for spark.

And all staters are AC not dc, the rectifier is what converts to dc voltage to charge a battery. When I worked on this system the salmon wire went directly into the stator IIRC, I'm thinking the other wiring is all for electric start.

********** is where I found most everything I needed for the wireing. If the brown and white wires are bad going to the points best to just buy them along with the insulater block that holds them where they go throught the plate. Those will give you big trouble if bad and not replaced with new ones as the insulation on them is old an will short fireing of the plugs. I'll PM you my number .

I know its been a long time since this was posted but I also would like to know where to get wires as mine are corroded.
