When i come to use it ive got 3 flashing lights and nothing going round.
When i put it in the charger the charger green light doesn’t come on , but the drill works (2 battery charging status lights)
Where is the problem – drill , charger or battery ?
I had exactly the same problem with my drill and was about to give up on it.
However, I noticed that it was a bit damp after being stored in the garage, so suspected that some moisture was affecting the electronics.
Here’s what I did to get it working again:
I undid all the screws in the casing and separated the two halves. At the bottom by the battery connector is a small circuit board. I removed this (still attached to the wires) and used a hair drier to blow it with hot air all over for a few minutes. Make sure you blow all around the little chips – this is where I reckon the moisture was getting and upsetting the circuitry that controls the speed. more details
