I took the condensing unit apart and follow the 24V blue wire inside

http://e-pixel.net/AC_condensing_unit_inside.jpg the blue 24V first
goes into the "red thing" (don't know what it is)
and then it goes into the green thing. When it comes out, there is no
voltage on the wire. There is voltage (27V) when it comes out of the
red and changes from blue to yellow wire but no voltage coming out
from the green thing.


What is the red and green ? how can I replace it as it seems to be
permanently attached to the pipe?


The yellow wire that comes out of the green goes to T1 on the
electronic board: http://e-pixel.net/AC_condensing_unit.jpg. The
other
24V is on T3.
So I have no voltage on the electronic board. Can I skip the green
and
red parts inside the unit and connect the 24V wire directly to T1 on
the board?

1. First shut down the 24v power to the condensing unit.
2. Cut the wires going to # 2 pressure switch about 6" to 8" from the switch
and tie them together to bypass the switch.
3. Turn power back on and see if it works then turn back off.
4. If it does then find why the switch was blocking power. Could the switch
be defective or has it sensed defective pressures?
5. If you are not sure what to do then find a HVAC person that knows what
they are doing so you don't do anymore damage to your A/C.
