I'd suggest these:
1) Verify the voltmeter is correct.
2) Use a hydrometer to check the specific gravity of the battery cells, or take it to verify it is good. Just becuase it is a year or so old dosen't mean it is good.
3) If the voltage is oscelating 9-14 volts, have the alternator tested, AFTER you check for clean battery cable posts, and GROUNDS from the battery.
