Jus purchased it at the National in Chattanooga and the seller stated it was running just fine. Well the suspension spring was broken first off. Replaced it was a ST No. 2 spring. I think it's ok and not my problem as to why it won't run. It's been converted to 110 v. Has a voltage regulator on it and the seller said it ran just fine at 9 volts. Well, I've messed with it on different voltages from 1.5 v up to 12 v. Problem is, the spring won't wind. I can wind it manually. Spring appears to be fine. I watch the rotary pawl on the escape wheel raise a set of contacts every minute. Sometimes when the pawl raises the contacts, I get a click, clunk on the lower right side of the movement. I can see them move, but I don't know what to call them. However, throughout all of this, the spring never winds. What should I look for? Bear in mind, I know absolutely nothing about electric movements. Thanks in advance for any help.
