Hung pull rope and set unit off. Purchased a replacement. This is on an onyx bass pro with a 33 a/m replacement unit removed bobbin and cylinder. Followed directions and replaced bobbin. Question I have is why doesn't green indicator appear back in the window. Also puncture spike is still up and if I inserted the new cylinder I'm sure it would puncture it also. I have read instructions and watched u-tube videos. Do not want to mess up the one I just bought to rearm PFD. What am I doing wrong or is it possible I have a defective unit. This is basically a new PFD.
