alternator or voltage regulator...I think

Had to resurrect my 1990 9KT. It's been sitting in the yard since last summer. I disconnected the battery terminal while it was sitting. I put it back on the road and it's been running OK for sitting so long. Since I started driving it again the battery light has been coming on when it is first started up. The voltage on the EDU is low....less than 12 V, actual voltage, not the "frozen" reading you get on start-up. If you let it idle for a little while the light would finally go out and the voltage would jump up to 13.5-14.5V. Other times I could rev it a little and the alternator would start charging. I drove it to work this morning and it acted as described above. On the way home the battery light never went out and the voltage kept dropping and was about 11.3V when I got home. Out of curiosity I left it idling and got a wrench and disconnected the positive terminal of the battery and the engine died. I called around and, of course, the local parts stores don't have an alternator on the shelf. I was thinking of trying to change the voltage regulator first. What are the odds that my alternator is OK and it's just a bad VR?
