I really screwed up and reversed polarity to the dc power supply
turned on power supply but NOT radio surge in current then 20 amp breaker in k3 poped I reset it amazingly k3 still works but something is wrong with the KPA3 or the PAI/O controller gives hi current if try to bring power above 12 w will drive KPA 500 to about 200 w with 12w if you try to increase power beyond 12 w hi current displays and KPA 500 is quickly overdriven as if the KPA3 is out of control increasing power in large increments (KPA500 is usually driven at about 20 w) is this a computer glitch i can fix or do i need a new KPA3 or PA I/O module?
