I am working on an Intermatic T101 timer. The unit is not turning on the lights at the expected time. I inspected it and saw that motor is not rotating and replaced it just today, unfortunately the motor is still not working rotating. I left the lights powered on by use of the 'manual on position' over the weekend, but I was informed it had turned itself off. This might be the work of pesky tennants, but just to be safe, I removed the trippers off the clock dial. Is the unit itself most likely to blame? I inspected it and found nothing obstructing the gears but I was unable to rotate them myself with a screwdriver. Thoughts?

Usually one of the gears is moving where you can see it rotate.
Take note of the time, If there are no trippers, tennants may just manually turn on, and you can tell if its advancing by the time changing.
These timers use different clock motors(old style and new style) be sure you have the correct one, be sure voltage is correct and the line provides power to timer motor(usually 2 white or black wires).

I removed the trippers because I thought that they might be overriding the manual setting after a 24hour period. I am 100% on the motor though I bought it directly from intermatic. I'll go back down in a few days, maybe I have a bad connection to the motor.
