Neutral Safety Switch Wiring Oddity

This might be difficult to understand but I'll try.
During "testing" (not guessing) if one of our members is asking for help and goes to the switch and puts a 12v test light on the exposed terminal of the purple/white and the test light fails to light he is going to assume at that point there is no power coming from the ignition switch because he was testing the WRONG wire.
We've all experienced these little wrong turns while diagnosing an electrical problem ,which for some of us is a momentary hmmm but for a rookie it can have him dropping the steering column to inspect the ignition switch and then "Corvette electrical system overload".![*****](https://www.corvetteforum.com/forums/images/smilies/willy_nilly.gif)

Hi Paul,
Welcome!
First Post! I'm glad you're here!
I believe you'll find that the 12 gauge purple wire runs to the solenoid on the starter in one direction, and to the ignition switch in the other.
Regards,
Alan

Hi Paul,
Sometimes bubba felt he didn't need the safety switch and ran a wire to by-pass it.
Have you looked for any sign of some of his 'add-on' electrical work?

Some people can get really creative and create a wiring disaster.

Hello All,
I am glad I found this post. I am having some difficulty with my NSS on a 1975. Took apart the shifter and notice some cut wires. The PO put in an inline 20 amp fuse. Fuse was blown. Replaced it and she started right up. Problem now is it continues to blow once I shift to N. Checked the wiring but do not see anything out of the ordinary. But then again I'm learning. Why bypass the switch?
