The alternator is coming out tomorrow to test it by itself.  I'm
considering a GM one wire if it is bad.  Let me see if I understand
this correctly - I run a single wire with an inline 30 amp fuse from it
to the positive terminal on the battery, and ground the alternator - is
that all?  Do I completely ignore the built-in alternator wiring
running to the driver's side (stock alternator location), or do I
re-route one of its wires over to the alternator?

Thanks,
Adam
