I got the kit this morning. Erected in the garage for now to play around with it. It did come in original box and everything seems to be in top shape / new. however, I've few questions.

1.) Seems like the timer is not working for me, not sure if I'm wiring it correctly from the pwer supply. When I put the timer on lights On for focus the lamp insdie the head comes on. But when I put it to exposure and press the relay switch for timed exposure I do not see the the lamp being turned on. Note: The door to the head is closed, Im looking under the bellows.

2.)Should the fan inside the head be running all the time? or is it on a thermocouple and only turns the fan on when it gets hot in the head unit.
