Before you toss your broken tools in the trash it’s worth a bit of time to see if it’s repairable. In a day when even the manufacturer just replaces boards and doesn’t actually troubleshoot and repair their own equipment it can be a bit tricky though. In the not so distant past you could find lots of schematics inside the back cover of user manuals that came with electronics, those days are unfortunately gone but that doesn’t mean it isn’t worth a look under the hood to see what the problem is.

In this case Webby from Elektrickery inherited a battery operated drill with a dead charger. Turns out that there was a thermal fuse that was blown. Webby could have just replaced the device and buttoned the unit up but he wanted to prevent the thermal fuse from popping again so he installed a cooling fan. If you look at some of his other repairs you might see a trend.
