Only when first starting outside ac unit, I have to hit the trip connecter on the conductor to energize compresser and fan unit.If I take my hand away,it will stop,3 min to 5 min later It will kick in,thermastat is at 78,when its'80 outside.after an hr I can turn it back on immediately without messing with the conductor

Many condensers have a 3-5 minute time delay device upon initial start up. Completely normal and saves your compressor from hard starts.
