If you actually changed places of your two power packs, connecting the Tech II to the wires of your old MRC and vise versa, and you still have the same problem with the Tech II, then I would tend to believe that you have a problem with the second block. Don't forget that elecrical gizmos ( Tech II power pack) wear out just like regular machines---- sometimes all at once, and sometimes over time. I believe the Tech II is a solidstate device( you know-- transistors, capacitors, diodes et cetera all mounted on printed circuitboards) as opposed to your old MRC power pack which is just a bunch of wires connecting switches, reostats, transformers and the like. On occassion the electronics, as they age, become sometimes less sensitive, or possibly, in your case more sesnitive to the outside world( your layout). I would say that there something triggering your Tech II somewhere between where you connect the wires to the back it and the track of block #2. Using your VOM on the more sensitive scales your going have to test all the wires and track in block #2. You really don't care about the other blocks because there aren't any problems there. What your looking for is a small short circuit that wouldn't be detected by the old MRC power pack. It could be something as simple as a couple of wires rubbing together and exposing bare wire. Look real close-- what would be nothing to would be really, really big according to your Tech II. Look real close at the points of any turnouts on block #2. Does the power that you use to opperate your switch machines in block #2 come from the Tech II, the old MRC or from a dedicated power source. If it comes from the back of your Tech II, then your going to have to test those circuits out, also. I know it can be a bear, but your going to have to be meticulous(sp) in your investigation--- you may even have to use a magnifying glass--really! I hope I scared you too much.
