To make a mistake once is forgivable, to make it twice is foolish but to make it 3 times in 5 minutes is sheer stupidity.
Went to put my motorbike battery on charge. disconnected the Live cable and hooked up the charger, Err came up on the display.
MMM flat battery or dud charger, tried a second charger, still would not work so got out my old trusted charger and then light bulb moment.
I had connected the neutral lead to the neutral terminal of the battery but the live lead to the live CABLE!
