I've had my Victron 602 installed in my motorhome, which has 6 solar panels, a morningstar mppt controller, and 4 LS-16 AGM batteries. The problem is that often the display goes dead on the Victron. Sometimes I can jiggle the wires at the shunt and it will come back on. Sometimes it comes back on by itself. Sometimes I can unplug and replug the wiring coming into the back of the display and that works. The wires are clean, with no corrosion, as are the connections at the shunt. I tend to suspect the wiring at the shunt, or the shunt itself. Its very frustrating. This was installed in 2012. Firmware? Other thoughts? Replace with a new 712 and replace the shunt?
Thanks
Charlie
