Actually, I need to test the current draw anyway. Plus, I can't exactly test that "on the bench" because I can't disassemble the furnace to get the relays out. Easier to test in place, using zones that won't cause local interference. In theory, I can use a spare transformer, and just shut the furnace itself off, to test the relays in the furnace. > The K24A pins pressfit in an 0.040 hole. OTOH I'm not sure my *scope* is good enough :-P But yeah, I'm going to keep test points in mind this time around.
