IIRC, some running electronics won't work if given less than a 9.0V supply.

Basic stuff with a voltmeter:
Test disconnected(no radio/alarm/etc parasitic draw)
Test connected.
Pull the fuel pump fuse and test while cranking.
Start and test what the alternator is pushing at idle and 2500rpm.

More than 3-5 years old and it snows there? Replace.
I just replaced my Diehard mfted in 2006.
