[Vwdiesel] Changing from external v. regulator to internal v.regulator alternator

Thanks Sandy.  It ended up that one of the mounting
tabs on the bunny alt was off just enough to not allow
it to fit.  :-(

The stupid auto parts store changed to a new
alternator tester that won't allow them to run it
unless a correct part number is entered, and just
gives them a pass/fail reading.

They all hate it because unless there is a cross
number available, they can't use it.  This is
especially frustrating because they can't do things
like tractor and boat alternators anymore.

Because of the simple P/F reading, they can't tell
exactly how many volts, etc are being put out either,
so they can't know if it is maybe on the edge and
about to die.

As a result of the stupid corporate people, they
couldn't test my boat alt either.

Because I had checked all the wiring and had no output
from the boat's alt, I went ahead and purchased a new,
basically generic GM 3-wire alternator.  

Now, the AMP gauge has a reading!  (No idiot light.)

Thanks for your help though.  At least I learned
something in all this!
