The only time the outdoor unit should be running is if the stst is calling for cooling.

No, it's not right.


TURN OFF POWER, and remove the t-stat, and should only be one wire going to G and also only one wire going to Y.

Are these wires alone? or are they jumpred over to one another?

They MUST be alone.. R may have a wire going to Rc.

I would remove the wire on Y at the t-stat and see what happens.

If the outdoor unit don't run then sounds like a defetive t-stat.
