Hola,
have an Hitachi UC 18YKL Li-ion, Ni-MH and Ni-Cd battery charger which as far as I know, overheated and failed due to it being connected to 127V instead of 230V.
The chargers internal 3.15A fuse didn't blow, however one of the 2W resistors heated so much that it came off (and burned) the board, as well as causing the plastic housing to start to melt and malform. The resistor still reads 130 Ohms even though it has no colour. -
See attachments. The scorched bit of board is where the resistor lived. The last 2 pics are of the fuse with it's cover removed and sand.
Before I start removing and testing each and every component, by some miracle, does anyone have a schematic for one of these, or perhaps have experience with this problem?
Clearer pics can be taken in the morning.
