The front display of the unit reads the following: FAIL: Relay weld In addition to that the lights for the Line Boost and Line Trim were alternating between each other. I looked in the manual for possible solutions and they only one offered was to unplug the unit and the issue may reset itself. Well that didn't happen, still showing the same message. Oddly everything plugged into it still works but I am guessing its no longer providing any protection. Couldn't find anything online about this. Is the unit essentially dead? If it is dead can anyone offer a comparable replacement?
