I'm not so snart...
The last few days I've been putting in long hours in the desert, building large structures out of steel. In the evening, I bring a truckload of stuff that needs to be fixed back to the duplex. The last few weeks I've been frustrated with my Makita drill/driver. I bought this thing back in the 90's and it's the best all around tool I've ever owned. It's got an expensive habit of going through NiCad batteries (around $35 each) and lately I had problems with the charger. Again. Last time I found a used one that I bought.
This time I decided I'd fix it or replace the guts with a 9v charger that I had laying around. So I took it apart and found a little circuit board inside that everything was wired to. I remembered that someone once told me that most service techs fix circuit boards like this: if there's corrosion they clean it off and then test the unit. If it works, they button it up, charge you $25 and go out to dinner on your dime.
If the cleaning doesn't work, they heat up a small soldering iron and lightly touch it to each connector on the board, reflowing the solder. They test it, and if it works, they put it together and charge you $35 and go out to dinner.
If that doesn't fix it, then it gets into deep dark secrets of leaking or clogged electrons, of which I know next to nothing, so I won't go there...
But I've learned that I can do the first 2 things. And you know what? I fixed the first one with the soldering iron ($5.95 at Radio Shack 10 years ago-came complete with solder). The second one I will do tomorrow.
Don't have to be genius, but a good memory goes a long way.
