Harley Davidson Pinball, 2nd edition by

This repair is on a Harley Davidson Pinball, 2nd edition by Stern  made in 2002.  This game had the dreaded battery leak issue.  If the user forgets to change the batteries every couple of years this can happen.  The batteries supply power to the SRAM memory chip that holds settings and high score info.   Many users forget or just don't know how to redo the settings so they wait too long.  The alkali chemical in the batteries just loves to eat metal, especially metal traces on computer circuits!  This customer was lucky, we managed to clean it up and repair the lost traces.  This leak got both major boards in the game. The repair notes follow:
