1976 Corvette starting problems
I have a 1976 Corvette that I am having problems getting started. About a month ago I tried to start the car and when I turned the key it would not turn over, interior lights came on but no starter turn over. Checked when I had last replaced the battery and it was 4 years. Replaced the battery and it started right up. Ran the car for a while to operating temperature and also turned on air conditioning. Turned the car off and forgot to power down the drivers window to re-attach trickle charger.
Car would not start again. Looked at repair manual and the problem could be in starter solenoid, so bought parts to rebuild original starter. When I put in the rebuilt starter in it just started to spin and would not stop when I turned off key switch. Bought a new ignition switch on steering column under dash and also bought a rebuilt starter and installed. Tried to start again and acted like a bad battery again, lights came on but no starter turnover. Have purchased a neutral starter switch at shifter and I am waiting for delivery as it is on back order. I have cleaned battery ground on frame and checked if fusible links to starter all they are both OK.
What am I missing???

You could have a bad battery lead...internal to the insulation. Or, you might be missing the main starter ground wire from frame to right motor mount/starter bracket. (see recent similar post)
I suspect that the starter solenoid with your FIRST starter change was defective and that's why the starter continued to run. I also suspect that your car's electrical system has a "drain" on it when the ignition key is removed. The ignition switch and NSS replacements were likely unnecessary, even though your symptoms might have indicated their involvement.
Keep the battery charger on the battery overnight. Read the amount of charge from the charger before you go to unhook it. That charge rate may be close to the amount of current drain your car's electrical system is experiencing.
If, after charging all night, the car starts up fine, you need to diagnose the current drain[s] in your car with key OFF. (With doors open, the interior lights will draw current; remove those bulbs, if you want to detect other draws).
Use SEARCH function to learn how to diagnose electrical 'drains'.
