DSM300 intermittent

[Pavetwist]

This is just food for thought, but last summer my DSM300 was intermittent and was driving me up the wall. I couldn't correlate its behavior to any other issues (connections/voltage/software/hardware). What ended up being the problem was a separate toggle switch on my center console. Somehow a grounding wire on another switch came lose and was touching (brushing against) the positive side of the switch every now and then. The DSM300 is very risk adverse and as soon as it was seeing the change/grounding on the positive side of my system, it would go into reboot or blank the screen (protection mode). Because all of my toggle switches on my console are jumped from a single positive/ground connection source, the lose ground was causing issues to the entire switch panel.

Not sure how your system is wired, but I would recommend a security check on all power connections at the back of switches/breakers on the same power feed (low cost and only takes a few minutes).
