I read your FAQs and changed out the self-tapping water supply valve and the solenoid filler valve. Nothing.
Since this icemaker is tight to the top of a bottom freezer there is no access to look in the top of the trays, etc. Somebody suggested filling the icetrays with a turkey baster but there is no access.

Next, I'd unhook the icemaker so I could access the front module head. If I'm not mistaken, the icemaker is sidemounted on this fridge, so the whole icemaker has to come out to work on it. It's a pain, but that's Subzero fer ya. Then jumper T to H to initiate a harvest. Catch the water that comes out at the end of the harvest and pour it into the icemaker mold to see how it fills. Dump this and repeat a couple more times. Chances are pretty good that if you've gotten this far in the diagnosis, that inadequate water volume is the problem == bad module.

Arrgh.. I'll have to empty the freezer and demount the icemaker.

I attempted to cycle the unit by gently lifting the "fingers" but nothing happened. I removed the icemaker and tested the heated- got continuity. Tested the switch attached to the wire bail and could not get continuity. With an old unit like this, should I just drop $125 and buy an all new icemaker unit?

Since we last communicated I successfully replaced the icemaker in our 1988 model 550 Subzero bottom-freezer refer. The new icemaker worked flawlessly until the plumber came to fiddle under the sink. He also replaced the saddle-tee icemaker watersupply valve with an in-line valve. However, 4 days later it started to leak and I had to shut it off until I could get to it 2 weeks later. I repaired the leak , bled th eline to the icemaker and... nothing. I emptied the freezer and got in to hold the wire bale up and the over-ride switch ON and manually turned th egear on the front of the icemaker, gently, until it started to run through the cycle itself. The water filled and I replaced all the baskets etc. Next morning- nothing. I again reached in and manually started the cycle , ice cubes ejected, water filled. After work that day, nothing.

What does that mean, you "replaced all the baskets, etc."? What baskets?
Also, what is your freezer temperature?

Does the front of your icemaker look like Fig. 1 or Fig. 2?

Sounds like the thermostat inside the icemaker is bad.
You can test it with your ohm meter. Make sure it's at freezer temp (~0F) before checking continuity.

What prevents this from reccyling and filling again?
Given the history with recent work done on the water supply, I have to suspect that either something is clogging the screen of the water inlet valve or the inlet valve has coincidentally gone flaky (I've seen this several times on Sub-zeros).
