Ok y'all, I'm tired of messing with it. I've replaced every part of my AC system and it now holds the R12 charge just fine, but the compressor only kicks in when it wants to. I've tested voltage, bypassed the pressure switch, still not getting the compressor to engage other than every once in a while (when the stars align). If I run 12v straight to the compressor, everything works like a dream.
So, anyone know an A/C guy who works on old cars and would be willing to troubleshoot this? It's gotta be a bad wire somewhere between the controller and the compressor...I'm just tired of tracing wires and getting random readings (sometimes they are hot, sometimes not).
EDIT: Or, anyone willing to come over and troubleshoot the damn thing with me?

Updating this...found a shop that not only knows what they are talking about, but has people that are actually interested in troubleshooting and finding the issue instead of throwing parts at it.
Air Components in Mesa (http://www.aircomponents.com/) is a great group of guys. They previously made my new AC hoses (for a great price), but I didn't realize they actually worked on auto A/C. Called several shops who weren't interested in troubleshooting an R12 system, or even a system that old. Then a mechanic friend recommended Air Components for troubleshooting my issues and I am really happy with the experience. They are honest, no BSing, and even willing to let me do as much work and prep work as I can to save money on shop time. Told me exactly the part to look for after I drop the dash, how to test the part, and then said to bring it in and they probably have a new one in stock. Just an all around great experience. Shop rate is $80 something an hour, and my total price for a full recharge with die and all troubleshooting time was $91. Seemed really reasonable.
