MY MOM HAD A CD2000 That she wanted me to look at. I tested the charger and no voltage output..
What happens to these is t he nicad batteries short out internaly . Which causes the chargers to overheat and burnout as well. I ordered the new batteries and charger and fixed it for her because its small enough for her to handle. However, if I had it to do over again I would not fix it! It was a pain to do.
