Today I bought an Edwards school clock, plugged it in and was glad to see the hands moving. But I quickly noticed that the hande was sluggish. The second handhdoesn't fully stop but it but seems to slow down and speed up in waves. There are schematics on the clock for both wiring "as a part of an Edwards clock system" and "as an individual clock". In the individual clock schematic it has the red wire disconnected with "tape end of this lead". With the others three running "to convenience outlet". Well there were no loose wires in the clock. All four ran into the plug. I thought this might be causing the clock to be sluggish so I took it apart and found the red connected to the ground. I removed it, taped it. Plugged it back in and... Nothing. The clock hands don't move at all. Can anyone please help? I'd very much appreciate it. Thank you in advance.
