One more possibility that should probably be checked.
If there's a partial short (shunt) inside the solenoid, it would help
explain the large voltage drop as well as the apparent non-function(?) of
the solenoid. It may also mean that your switch contacts have been and
are being cooked. Not good. This might explain the change; i.e., the
resistance of the switch contacts has increased to the point where not
enough current is getting to the solenoid coil.
So, one more test would be to connect an ammeter in series with the
solenoid wire to check the current. Unfortunately, I can't tell you what
the current should be. Maybe someone else knows or has a good one handy
they can test (either actual current or resistance). But as a wild guess,
I'd say you should not see more than an amp or two (hopefully less). But
note that solenoids are pretty hefty devices intended to slam very large
contacts closed very hard & quick.
It might be interesting to know why the previous starter was replaced.
In any case, good luck and let us know what you find.
