I just left the shop so can't check the voltage at red light....

When I plug it, the yellow light turns on meaning charger is working and also green light on like it was full charged. But when I unplug it and turn it on, stuck here no movement possible, with the red light on, wrench key and battery icon that flash. Also, there is no code that appears.

Edit: on last friday a tech came and changed the break switch because the jack was stopping every time we turn right with it. Then all was good and used it all weekend. Then today I unplug it and boom dead lol
