1971 evinrude 40hp starter/solenoid problem

[Cgr]

I have a model# 40152G and have been trying to start motor using ignition.When i turned key nothing happened,I have cleaned all connections on solenoid & starter and still nothing.I have jumped the starter from 12v connection on solenoid over to starter and I started the motor.Have also put jump wire from small 3/8 nut above the small letter s on solenoid to the starter,turned ignition key and started the motor.Thought my solenoid was bad so I replaced it with a new one and had exactly the same problem.Don`t know what to do next,please help.:

If the solenoid is new and you are sure it is wired corrrectly the next place to look would be the key switch itself.
If it works then doesn't that makes me think the switch is bad, the good news is they are cheap and easy to replace.

Troubleshoot, troubleshoot, troubleshoot. Stop throwing parts at it and go to Engine FAQs, "Outboard won't start". Do the starter circuit troubleshooting.

Did you use a marine solenoid to replace the old one? If not, and you used an automotive solenoid, you will have problems because the two are not grounded in the same way. The automotive solenoid grounds via the baseplate, while the marine solenoid grounds via one of the small posts on it.

"Have also put jump wire from small 3/8 nut above the small letter s on solenoid to the starter,turned ignition key and started the motor."

That part doesn't make sense. Jumping from the battery + cable to the small "S" nut should activate the solenoid and make the starter run. If it doesn't, then the safety switch may be bad. The other small nut is connected to the safety switch which prevents starting with high throttle settings.

If you connect 12 volts to the safety switch by fooling around with improper troubleshooting or otherwise, you will fry the switch in an instant. Same thing if you use the wrong solenoid....guaranteed to fry the safety switch.

White wire coming from the main harness (key switch) goes to the solenoid "S" terminal. The other small nut on solenoid connects to safety switch. Connecting 12V to safety switch will blow it.

Problem was bad neutral start switch which is connected to small nut on
solenoid.Thanks guys.
