after having installed an AC coil and condenser the furnace blew the transformer. It was replaced with one with a reset. Issue remains. AC will start, cool but will blow the transformer reset after a couple cycles. I have checked all wiring with no obvious signs of trouble.

Check in the outdoor unit to see if maybe a wires between where it goes into unit and gets to contactor (like though pressure switches) and see if maybe a wire is up against a hot gas line that may be heating up and causing wire inside the sheatingto short to tubing.
