I may be able to help. My PS 160 charger is busted too working only
every once in a while and I took it apart. Don't know much about
electronics but everything in mine looks okay. The bands on the
resistor closest to the LED is from top to bottom Gray-Red-Gold-Gold.
This appears to be slightly larger than the resistor next to it. If
you want I can send you a closeup macro picture of the board. Private
mail me at and I'll attach pic.

I have a Black & Decker PS160 charger - 12V. It stopped working, so I
opened it up to have a look. There are only 2 resistors in these
things. One of the two resistors has blown, probably because I left the
unit plugged in for too long and ruined one of my batteries.

If you bought the original with a credit card, it's possible the
original warranty was extended by an extra year. Or can you buy a B&D
tool that uses an identical charger and look at it?

If a resistor blew, I would expect the power transistor or triac
associated with it to have blown as well. I hope it's a discrete part
and not built into an IC.
