Follow Up: Cd changer repair question
To those that responded, thank you VERY much!!
desoldering the jumper (blob of solder) on the back of the optical pickup for my Jeep's CD changer worked perfectly. So the next logical question is (purely out of curiosity), why is there a soldered jumper on the back of this pickup? Is it for different uses of the same device, or is it to keep "unauthorized" do-it-yourselfers from being able to fix it? Thanks again for everything! -Adam with a working 10disc changer! |

The solder blob is for protection against static electricity (ESD) to which
many pickups are sensitive, and can ruin them. Best to unsolder after plugged into the circuit. Mark Z. "Adam" wrote in message ...
