I have several bicycle computers that the harness have broken .some of them have a nick on the cable and others show no signs of damage .Does anyone out there know where to get replacement harnesses or how I would go about fixing t he harnesses I have.These are 'old' cycle computers out of style and I really do not want to buy a new cycle computer when what I really want is a new harness.I an particularly interested in the Echo j12 echowell? as I have several of those cycle computers because I liked the average cadence feature.I do not want to buy another cycle computer that the harness will probably break on and I will add to the collection of cycle computers with no functioning harness. I want to fix or replace the harnesses I have
If you can see an obvious nick trim back the plastic insulation and rejoin it. There will be two conductors so make sure that when they are rejoined they don't short together. Use tape and separate the soldered joins by at least 1/4 inch. Most breaks in the wire occur with in an inch of either the pickup or the holder so you could just try shortening the wire a few inches. ( If the holder and the pickup are not molded) Or just replace the wire. Any electronics store should be able to supply the wire. Most pickups have a reed switch which closes as the magnet passes nearby. They sometimes get dirt/water in them which shorts them out. A spray with wd40 can fix this. If the computer is OK you can get a speed reading just by shorting it's contacts together every few seconds. Good luck
