Hey guys I've got a crazy situation. I got called to replace a clock on a 26 zone system. No big deal except somewhere through my extreme caution I still managed to get the wires crossed up on the last 9 zones, and they are all the same color. I've already spent soem time tyring to eliminate 1 by 1 but no success. I have a volage meter, but I'm not real sure how to find the ground wire(s) a couple of the wires must be a jumper ground for the expansion modules (hunter ICC). Any thoughts?
