Garmin LVS34 Malfunction

A week before I left for Cuba,  I had a day on the lake when thing just go south.   The fishing on the forebay was slow but as the afternoon wore on,  my Panoptix Live view LV34 system started to malfunction around 2:00pm.    For some reason I started to get black triangles on the screen while I was in Perspective mode.

I suspected that I might have low voltage on the battery that  I use for the electronics.   Low voltage makes some electronics do weird things.    I checked to make sure a the cables were plugged in  properly and as I was checking the cables,  I lost all power to my GLS10 and my Livescope was unusable.   I couldn’t get excited about fishing the rest of the day blind without the Panoptix and headed for the launch early.

When I got home,   I removed the GLS unit and checked the wire harness for shorts.  Using a voltmeter,  I found the power cable and blown fuse that caused my Panoptix Failure.   It was the power supply cable to the GLS10.   After pulling that out,  I used a  voltmeter to test the cable.  It was shorting across the two pins.     I dissected the plastic sleeve insulation where I suspected the short and it was right at the connector to the GLS10.    After ordering a new cable and   I reassembled the wire harness and tested the GPSMAP 1042xsv and GLS10 on the boat. All the units powered up and appeared working.   I attached the old LVS34 is definitely malfunction.

Here are pictures of the cable that shorted out the fuse to the GLS10 in my boat attached to the 1042xsx


After replacing the cable.   I booted up both units and update all firmware versions on both sonars and both GLS10s with Active Captain.    After which I attached the LVS32 and the LVS34 to both units.  On both units the LVS32 was 100 percent functional.   On both units the LVS34 showed the black triangles.   There is definitely something wrong with the transducer.
