[Vwdiesel] '93 EV DSL - more bizarre goings-on

I'd double check that when you reinstalled the starter back a few months
ago, that you didn't leave the line from positive battery to the starter in
a position where it could rotate over slightly and contact the other starter
terminal. That could have run the starter motor on its own while you were
driving, given you the grinding sound, and created enough current pull on
the alternator to squalk that belt... RPM indicator runs off the alternator
also, right?

That's my guess - either that or a wire over that terminal shorted through
connecting positive to starter and bypassing the solenoid.

Briefly reconnect your battery to see if the starter motor is still engaged
and if so, move your positive connection to the starter slightly and see if
that stops the problems...
