Re: Neutral safety switch 1981 25 Johny
I'll take a guess. The safety switch is bad so somebody bypassed it by grounding the wire going to it. Am I far off?
Anyway, there are two small terminals on the starter solenoid. The wire from the key switch goes to one of them. The other one is connected to the safety switch. So check to see if somebody has been monkeying with the wires.
Some tests: Disconncet the wire from the safety switch. Starter now should not work. If it does, check for grounding as I suggested.
With the wire disconnected, check the switch with a multimeter on ohms test or continuity test if it has one. Ground one meter lead and touch the other to the safety switch wire terminal. You should have continuity in neutral, but not in gear. If you have continuity in both, the switch is shorted internally or out of adjustment. See if you can get continuity / no continuity be pressing and releasing the button. If you can't, the switch is bad.
EDIT: Caution, if somebody has replaced the solenoid with the wrong kind, it will burn up safety switches as fast as you can put them in there.
