Hello All,
has anyone repaired one of these - or have a schematic for the control pcb ?
D11 is cooked - a zener we think, along with it's feed resistor - the unit kinda works but the Volts display reads 1.71 or 1.72 volts per cell all the time
suspect some one put an 80V battery on it as it cooked the regulator ( now fixed ) but the uP sees too low volts, as above, and displays same
Any tips kindly accepted
