Ok, I just got my first Barr electric (battery) clock at auction today. As usual, someone left batteries in it and the contacts were corroded. I washed it all out with baking soda and water and sanded the contacts down. It now works and impulses, but after only 13 to 16 oscillations, it impulses. I read it should be more like 25 to 40 oscillations. I've never taken one apart before, so what needs to be cleaned to get better impulsing? Thanks!
