A/C problems

[coreyg67]

Ok, I have found two different electrical boxes in the bay that I am exploring.
There is a
gray box with a series of two relays of some sort (again I'm not an electrician
and have
no clue what i'm looking at) and then a second box that has a label of automatic
transfer
switch on it. I pulled the cover off of both switches and checked the power
coming in.
The first relay or whatever it is has 240 coming in, but nothing leaving the
relay. I don't
know if this is transfer switch as well, or what it is, but it is not passing
power through. I
then checked the power going into the next auto transfer switch and there is no
power
entering the panel. So, I'm assuming the first relay/switch is the problem, but
I don't
know what exactly it is. Thanks again for all the help everyone!
