Customer Question

Hi - I have a lowrance sonar (GlobalMap 5300c iGPS - mapping GPS receiver) which has stopped working. The power source is fine (I have checked it with my lowrance fishfinder). The unit has now been taken apart and cleaned, there are no apparent problems
Any tips?

Hi Jamie,

Check around the power connection - look for any damaged solder joints or damage to the connector itself.

Sometimes a strain on the cable can damage the connector joint.

If nothing is found, let me know if you have a voltmeter available to carry out further tests.
