At my Whits end with this problem.

Had continous issues with my sec meter.

Replaced 3 times with new units and works fine before I get the LCD meter NOT FOUND error.

Traced wires though the whole machine and can't find any breaks.

Cable seems to merge with logo lamps (top of the unit) but it seems to visit each individual lamp.

Anyone got advice on next thing to check?
Where the wiring ultimately ends up?

Meter display is working BTW just undetected??

Thanks in advance.
