I just replaced my timer mechanism and there seems to be a strange problem. The timer gears are only visibly moving when the timer is switched on manually. As soon as the timer goes off (I'm assuming) or is turned off manually (confirmed), the gears stop turning. I am stumped on this one. Any help would be greatly appreciated. I tested the lines to the timer and they are live when the timer is switched on or off just as they have always been and the timer kept time for years until the motor went out recently. Clueless.
