Clean the circuit board on a Gottlieb rat trap reel
Steps
- Remove the three screws holding the metal reel to its cam; leave the cam shaft clip in place.
- Polish the board traces with 400 or 600 grit paper.
- On refitting, line the reel's one larger hole up with the larger pin on the nylon hub, not with a screw hole.
- To reach the nine, zero and EOS switches, remove the board's two screws and slide it out.
