Drill Battery Charger

A few months before I moved to sunny Scotland my dad passed on his nice bosch drill set, which kicked around for a while and now that I want to use it, I discover the charger's dead!

To the workshop, Batman!

Disclaimer: this one's got mains in it, don't try it unless you know what you're doing. and even then it's not my fault if things go tits-up


After a spot of continuity testing I found the primary winding to be open circuit. Very odd...
I mentioned this to a former partner in crime who suggested it was probably a thermal fuse, so i pulled some of the tape off the primary and found it.
I then bypassed it with a bit of wire, creating what is known in the trade as "a bloody deathtrap" and gave it a quick test.

Everything worked fine so i ordered a replacement fuse and a small fan to keep things cool in future.
*Fast-forward 2-3 working days*


Good info... I'm keeping this in mind...
