Thread: Kill switch problem

What motor? Make sure that ground is good all the way to the motor.

150 optimax I guess I'll Chase the wire to the motor I had my switch replaced àwhile back could that be it.

Ohm out the switch to make sure it has continuity through it: Disconnect switch from outboard, no power to switch and then use volt/ohm meter to verify switch is opening and closing. If it doesn't close it will not work.

I put in a new switch and it still isn't killing the engine also checked the ground wire at the switch and it has a good ground.

Still sounds like a poor ground. Use a ground directly from the battery when testing. Check voltage on both sides of the switch with the switch activated. If you have any voltage on the switch you have a poor ground. If no voltage at switch check the 12volt + wire for a poor connection or partial break or corrosion.
Hope this helps.

Does the key switch kill the motor?

Yeah, if the key switch works properly then you have a defective kill switch or its installed wrong. Simple quick test can be done with an ohm meter. Turn the key on. Find the black/yellow wire at the switchbox(s). Put 1 lead on it and the other on a good ground. With the kill switch in the run position you should see an open circuit. With the kill switch tripped you should see continuity (very low ohms).

I put a new kill switch in and it's doing the same thing what's the chances of a new one being bad
