Tested the charger last night. Worked perfectly.
FYI: When I called Bosch Canada for a repair of the external charger, they said to dispose of it and get a new one. I then opened the charger and found the 2 x LET50 fuses were blown. New ones are about $100 each, I found used ones for $18 each including shipping. They worked perfectly! So check the fuses in your Bosch before throwing it out!
Cheers and thanks for everyone's feedback!
