I am using Mercury SRS for less than a year. I have bought it on 2017 pro-wing.
It was working perfectly until last weekend wile I took my batteries out as usual for charge.
after charging, I have plugged battery one and immediately the unit started to work regardless to the switch.(the switch was at off position)
after few seconds the monitor showed "Regulator malfunction" message. The switch is not affecting battery #1.
Battery #2 is functioning normally.
The system is running with this setup for almost a year without any issues
Please advise if there is anything I can do or I must send the unit to you for repair/replacement
