The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."

Wow, I wish I could install a complete split system in 3 hours...
For me its more like 2 days, i would think that if you replaced all the old low voltage wiring from the indoor unit to the thermostat, and from the outdoor unit to the indoor unit that should of fixed the problem.
The next step for me anyway would be looking for wires chaffed at the entry and exits of the units and at the thermostat.
I have seen units blow transformers due to Shorted RV, Shorted Gas Valve, and a shorted contactor solenoid.
