Need a little help over here......

I have a condo.... with a two part Bryant A/C system. One part is the compressor and
squirrel cage blower vented through a brick wall to the outside. The compressor pumps
freon to a ceiling unit which contains blower and distributes the cooled air into
ductwork.

A/C system is not turning on..... I'm not getting 25 vac ac to the wall unit.
Backtracking the wire...it seems that the low voltage is generated by a transformer
and relay in the ceiling unit. Line Voltage is present on both units, but a
measurement on what should be the low voltage circuit does not show any voltage.

Argh! I feel for you.

First, there should be a controls diagram *somewhere*, probably
at the ceiling unit.

Measure if there is 24V right at the xfmr terminals. Work from there.
