'78 master craft neutral sensor

I have replaced everything between the ignition switch and the starter.. solenoid, you name it, everything checks out good. But I still have nothing when I turn on the key...lights and blower work, but not even a click.
The only thing I have left to change out is the sensor on the tranny that must engage and disengage when starting...I'm guessing!? Like a safety?
Anyone have any info on the little gizmo.
There are two wires attached to a nut...which attaches to a three bolt housing ( small) on the exterior of the transmission itself. The nut separates the wire housing...I guess what I need to know, should all of this be replaced...or just the electrical housing?
One day it fired..the next day nothing..
Any help would be much appreciated.

Not sure if this will work but u may connect the to wires together and see if it will start. I think it may b like the safety kill switch. I know that will work on it mine is by passed know due to a faulty switch.

It is a neutral safety switch designed so that you can't start it in gear. You can test it with an ohmmeter if the power is off, or with a voltmeter with the power on. You are just looking for continuity. You may find you need to disassemble the throttle assembly and clean it out. My '77 was having a tough time getting the throttle just right and when I opened up the throttle housing, I found original grease which was almost petrified and half a beach worth of sand.
