Hi All

I've searched the wonderweb but can't find an answer to my problem...I have a Bosch PSB 18 LI-2 cordless drill which worked well until recently, now it's stopped.

There was one temporary stop before it finally stopped - I opened up the case to see if there was anything obvious going on and the drill worked again when put back together so I thought all was well and I'd just overloaded it and some protection circuit had kicked in.

A day later, it stopped again and hasn't worked since. I've tried two other batteries and they're all fine in my other drill. There weren't any unusual noises or smells to give a clue and the three LEDs and the light all work on the dead drill, so I guess the swich is ok...any ideas or things to try please?

Thanks.

Stripped the drill down again last night and it started working again! Pretty sure I've found the problem though.

Loose wire to the motor...looks like it was badly soldered from the factory because there's a large blob of solder about to fall off the tab therefore very little solder around the wire....hopefully an easy fix.

Thanks for your help...

Hello wrinx.
Nice one for posting what worked for you. I'm sure it'll help someone else down the line.
It's surprising how often a strip down and clean out can work for sorting power tool problems. Obviously in your case it allowed you to spot an actual connection fault.
Cheers.

I actually stripped it down again to check whether the brushes were worn out, which I believe involves a fair bit of surgery on the motor casing to get at them so I'm happy the repair is a little less involved.
