moving wife's 75 vette in for winter. Crank crank but no start then turn key and nothing. Prior year I had change solenoid for similar reason but at that time found burnt ground wire. I change ground and solenoid and all was fine. Then the above occurred. I am at a loss. Very low voltage at neutral safety switch and nothing at relay or starter. All lights, dash, radio, hazards, back up lights a seem perfectly fine. Also just replaced battery, what's next? How should I proceed?

Have you checked the connections at the steering column where the ignition switch hooks to the harness? Definitely a connection problem. Where do you live that has winter in the middle of July?

I meant when I was putting away last winter. I'm in Michigan. I have not check ignition connections yet but was intending to do that. I was also thinking of re cleaning grounds at starter even though had just done so.

Neutral Safety Switch.

Is it an automatic or manual transmission?
