Not Charging When in Outer Case
The pcb on the toothbrush was shorting & had blown the F1 fuse. Obtained a replacement board from China, removed old & replaced with new. When the brush without the outer casing is placed on the charger, it charges with green light flashing. Brush also works as it should & can be reset. So I thought great, fixed! But, when I place inside the outer case & place on charger, it no longer charges, green light does not flash. Brush will switch on but just does not charge. Does anyone have any thoughts on why this is happening? Many thanks David
So the outer case is a hollow shell with an end piece. There is no electrical contact, presumably a current is induced in the coil to recharge the battery. As you can see from the attached video all is ok when the case is on. Thanks for taking an interest.
