It would be impossible to say without a compression test compared to
some original specs. How about voltage at the battery while running?
What is the amp rating of the battery? If it didn't have a starter that
was up to snuff, and it had enough compression, you might be right about
that. The solenoid is cheap; replace it. Check the basics first.
Check the starting and ignition circuits for obvious faults. Check the
ground strap. Replace the voltage regulator as well, they're cheap,
too. These circuits are prone to failure. Make sure everything is
clean and bright and no arcing is going on.

They came with ammeters. You'll have to use an external voltmeter or

Check the other things first.

Sort of out of practice, no? Regardless, just look at the things
responsible for starting it. Cap, rotor, plug wires, points, dizz, pull
a plug or two, etc. Assume nothing with a 40-year-old car.

I don't do that. Just check back here.
