Dead C36 - Help!

[onewhippedpuppy]

Last night my '95 C36 was totally dead after work, no lights, no cranking. I had the battery tested, it was shot so I replaced it. Today it starts acting funny, with the ASC, ABS, and SRS lights coming on at a stoplight. Also, the turn signal blinker started blinking erratically. Giving the car gas made the issue go away. I headed home quickly. Battery tested at 8 V, now the car won't start.

So, I'm thinking dying alternator. Any surefire way to diagnose prior to dropping the money? Anything worth cleaning first? Is 97k miles normal for a '95 C36 alternator?
