Warning Light Cluster problem

FWIW, I ended up picking up that 110A alternator from AceAlternators on ebay. I have no means of measuring current draw to verify the 110A upgrade, but here's the voltages I'm seeing with it:

@ 750 RPM idle, low beams on + fog lights on + A/C fan on max = 12.6V. Nudge the idle up to 850 RPMs or higher, and it goes up to ~13.6V.

With same loads switched off, from low idle and up nets between 13.6~14.5V.

Also I have an alternator installation tip that might be useful if anyone runs into the problem I had. This particular alternator didn't want to slip over the water pump housing at the pivot point - it was maybe a few thousands of an inch too tight, and there was no persuading it to fit. After much cursing, and considering shipping it back, I had a brilliant idea... Just loosen the 4 bolts that hold the alternator halves together about a 1/4~1/2 turn each; that "spreads" the alternator half's just enough to get it to slip over the water pump housing pivot point. Once the pivot bolt was in, I just tightened the 4 alternator bolts back down and everything was fine.
