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.
