Alternator Issue - Update

Original post included below for reference.

I replaced the alternator - rather the shop did - I couldn't get the top two
bolts out. They ended up breaking one off and had to drill/sleeve.
The new alternator fixed the problem of the brake and battery dash lights
being dimmly lit. I still only get about 10.9v on the CC head when the A/C
is on, battery reads 13.5. With just the heater fan on, CC reads 12.3 -
battery reads 13.7 and with just the engine running, CC reads 13.6 and
battery reads 13.8. At present, I am not going to worry too much about the
mis-readings on the CC head. The dash gauge reads just shy of 12 when the CC
reads 10.9 and battery reads 13.5.

Thanks to all the replied.
