I have started my Commando after fitting a SH775 reg/rec , and sparkbright led voltage monitor , the battery is a Motobat 9 AH,and three phase new Lucas stator, with the headlight off after a short ride the led is flashing red and green (said overcharge , according to spark bright it's over 15.2 volt) , with lights on , it happens over 3000 rpm, tested at home with the Fluke multimeter confirm high voltage , fit another SH775 (from another cdo I have ) same voltage ..............!! could a bad battery do this or what else , cannot imagine two bad reg/rec , but ??
