I am in desperate need of a wiring schematic for a black and decker 1 hour battery charger model # PS1518BU if anyone can help me PLEASE EMAIL ME @ toolguy9@tampabay.rr.com. I am looking for the value of a reisitor on the board and Black and Decker is fighting me telling me they don't have it in there records and I would have to buy a new charger (cheap generic that is not quick charge)
