Hi Guys.
I bought a B&D drill some time ago.
The drill had had very little use, as it was for general DIY.
Charger Model: 486910-11
Battery A9277
A while ago i noticed the battary ran down, when i went to charge it the Red charge light monetarily flashed then went green to say its fully charged.
The battery never charged again. I though the battery had seen the last of its days.
Randomly i pulled the drill out as i needed it urgently.
I checked the terminals and found it held a steady 6.12 volts without charging.
Randomly i smelt the charger and it smelt burnt, so i opened it. As suspected i think i can see some damage definitely to a resistor and maybe some transistors.
See pics:
I tried to desolder the resistor and the shell crumbled. Eventually after googling I found what the resistor was.
These are the components i THINK are damaged:
1. 29 Ohm 5% resistor (Red Red Black Gold).
2. A1757 Transistor
3. S9012 Transistor.
Do you think the damage was limited to the transistors and the Resistor? or should i just chuck it and buy a new charger / drill? (Would rather not if this is a few quid to fix).
Thanks
