My father-in-law sent me home with yet another car battery charger to fix. He buys them at the auction and if it doesn't work he asks if I can "take a look at it". Today I finally found time to take a look at his latest auction battery charger. The problem with this unit was that the analog meter's indicator needle wasn't sitting in the correct location - it was pointing midway on the dial. I assumed it was broken and that would be the end of the story. Nonetheless, I decided to take it apart to see if I could find out why it was broken. A couple minutes later I found out that I was wrong. The meter wasn't broken. The needle was in the incorrect position because a thick spider web was holding it there - from the back end of the needle to the meter housing. A quick dusting and the needle was back in the correct position. If this would have been a money job that would have been all gravy.
