I am trying to repair this charger and have narrowed the fault down to the surface mounted components on the PCB. However I cannot find a schematic anywhere. Does anyone have a schematic or components list?
The full charger Part number is BC190/808 and the PCB part number is 1194V0Z. One SMT component in particular I cannot identify is just marked '431' and seems to be a SOT-23 package. I have tried contacting Fluke and the PCB manufacturer (Hong Kong) without receiving a reply. Naturally I could just buy another Charger but it is more interesting, and £80 cheaper, to try the fix. 😕 Can anyone help please?
