Scoreboard Fixed

One of our senior students troubleshot the scoreboard on the field today and found a faulty 1/4 inch TRS cable, Using a ohmmeter he ringed out the cable and found that the tip and ring were open from one end to the other. He then took it back to the shop and repaired the cable.

Picture of the broken cable, can you see the break in the wire?

Answer: No, this couldn't be seen visually, DMM is needed and the knowledge of how to use it.
