Thanks - I took the alternator in and got it serviced and as a result the
red indicator light stops coming on and the battery is charging. There
does seem to be a draw on the blue wire though which requires more work on
my end to locate and fix.
Thanks for the follow up. I'm getting pretty good at removing and
installing my alternator.
