LOL! I've made a fair amount of pocket change over the past 65 years- - - - -by knowing what to whack- - - - -where to whack it- - - - -and how hard! If that doesn't work, then the test equipment comes out!

When I was running a Tennessee state trade school auto shop, the assistant director of the school told me his pickup wouldn't start. He lived about 20 miles from the school. I suggested that he might try to tap the starter with a hammer to seat the brushes temporarily. It came in on a wrecker the next day- - - - -with bunch of big dents in the WINDSHIELD WIPER MOTOR!
