Hi all. I have a Dye M2 Mosair which I use for walkons about once a month. Last month for no apparent reason it wouldn’t switch on without being plugged in. When I did it said the charge was about 30% and then When I got it up to charge it switched on and off fine. However, when the marker was switched off the grip LED would flash red. Not the eyes error short flash but a long one second flash. Today, I’ve pulled the marker out of the bag ready for tomorrow and it won’t switch on again. Same issue as last month, the battery is drained and now I’ve charged it it’s flashing red again when switched off. The only google result for this I’ve found is a PBNation thread where it’s suggested that there is a problem with the board although Dye Service suggested it was the battery. Any advice or help would be appreciated. I've reset the marker to factory and updated to the latest firmware but the red flash is still present. Thanks.
