I have to be doing something wrong on my end. I have built about 20 SSCs, V2 converted to V3, and out of the 20, 7 of them are dead on first build and 3 will run the test firmware, but I cannot get to program with the SS Utility. Last year I built over 40 SSCs with only 2 or 3 failures, but none that were dead on first build. I have been soldering for a very long time now, but I am obviously doing something wrong with these. I have taken 2 of the dead ones and replaced both the pic and the 485 chip. Touched up all solder joints. One of them I even replaced the 5vt and 3vt regulators with no change. Any suggestions?
NOTE: Dead= PIC 3 will not recognize device, ie. cannot program pic
