Hard reset of 6.1 control panel to “reset” battery status

[mattandlisagbr]

Unplug the 2 pin plug from the sensor on negative post of the battery.

Wait 30 seconds or so.

Plug it back in.

Bringing this old post back to life as it just solved a problem with my GC680. Basically, control panel correctly reading voltage but had the wrong calculation for percentage power left. Disconnected the sensor for 30 secs and now all is well. Huge thanks as saved me a trip to the service centre and saved my planned weekend away
