Okay, here's the situation:
'70 MGB, intermittent starter failure.
Twisting the key will always trip the relay, which will *not* always engage the
solenoid. Three basic modes:
1 (95% of the time) Turn the key, starter works, car starts.
2 (4.5% of the time) Turn the key, relay clicks, nothing else.
3.(remaining .5%) Turn the key, starter spins, but does not engage.
1 and 3 can take place on subsequent key-twists. 1 and 2 (or 2 and 1)
have been happening on opposite ends of a drive or mechanical work. (push it
started and drive home, when I get there it works again; or, for example, pull
the starter, bench test, re-install, and it works again. For a while.)
This is a bit unnerving (esp. #3). Any thoughts/suggestions?
The starter is less than six months old, 5k miles ago (3 months) the flywheel
was inspected and was not missing any teeth, the car has no other electrical
problems (touch wood).
