    Coleman evcon
    I installed a Honeywell digital thermostat for my parents, which I have done myseld with no problems before. Foolishly, I didn't notice that the coleman evcon system has a couple more wires that the honeywell didn't have a place for, so I undid the wiring, and hooked the old therm back up. Note: I didn't cut the power, and I know a couple of the wires touch for a moment or so, not long at all. Anyway... the system won't come back on now. My multimeter is not reading any power at the thermostat. Any ideas on what may of happened and any suggestions?

    Check the fuse that could be on the circuit board if so equipped. Also check the 24 volt transformer.
