Tried smacking the controls, Believe it or not-it revealed a loose wire which I soldered back into place. Still couldn't get it to work. So I tried switching out the 3 circuit boards one at a time. Results! one now works and found a cracked board tht must be replaced. Contacted Moto and the can get me the board, also ordered some spare gaskets for the guns. My wife likes to see her rounds hit my tank, rather than just hear it with the IR sets. She usually kicks my backside because she is so unpredictable. Anyway Thanks again for the help.
