Ive had Demo Man for awhile and all of a sudden the claw is not working. Ive done the claw test over and over and it wont reset. According to the manual "theory of operation"by running claw left and claw right both need to show the optos as open to work. Ive ran both as far as they will go and the optos wont open at all. How can you test optos in the claw? Ive never taken one apart? Thanks in advance
