trying to trouble shoot a black/decker charging unit.....it over heats
quick and hot......I replaced all components but still over heats....help
.. thanks

The B&D cordless I have can't get hot as it has a thermal fuse bound into
the transformer primary - or at least it did until the pack developed a
couple of shorted cells (normal for B&D!) although they do run warmer than
you might expect in normal operation.

You can easily tell if it has shorted cells as the transformer primary goes
O/C and stays stone cold when plugged in.

Does the charger overheat when plugged into the AC power but no
battery plugged into the charger?
