Exercise bike repair

Today I did a service call to Elora to repair a exercise bike this bike is worth over $2000 brand new but this lady bought a used one on Kijiji for much less. Well it only worked for a few weeks before it stopped working.

She phoned the company that made the bike and they sent someone to have a look they couldn't find the problem.

I went to have a look there was no power to the LCD screen so I knew it was something to do with the power.

The first thing I tested was the power adapter it was 9V DC and it was working, the next thing that I check was the connectors and low and behold one of the connector wires was broken.

I re-soldered the wire and it worked.
