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.

Black & Decker has not been able to help. The warranty is over, so they
told me to buy a new one. They said they don't have records of what
parts were used in the charger. I've looked high and low for someone
who might have a schematic, but no luck.

Here's what I'm pleading for:
I need someone who has the PS160 charger to look at the circuit board
and tell me the colors of the bands on resistor R2 (there is a label
visible under the resistor). It's the one right next to the LED. My
resistor is burnt and I can't see the middle band(s) at all. It looks
like one end is a brown band, and the other is likely blue but might be
green. Can't be sure because of the damage.

As always, any help is greatly appreciated.

I have three of these chargers. The load resistor on each was burned beyond being able to see the band colors. Two of the resistors measured around 6 Ohms and one was 9. I got some 10 Ohm 1-watt resistors from Radio Shack. Work OK but since the 1-watt resistor is bigger than the original you need to drill a little hole about 1/8 of an inch beyond next to the diodes after the burned resistor is removed to put the lead in and the bend it over to the connection point. Also, one of the transformers was dead. Looked in a junk store, such as Goodwill and found a power supply rated around 12 - 14 VAC. Fixed mine with one that said 13.5 VAC.
