I'm not getting 24v on the contactor. I am checking between Y and C and I'm not getting voltage. However I am getting voltage between Y and R on the control board. I checked the R-22 pressure and I'm getting 136 on both sides with the compressor off and the Hi and Low pressure switches are not connected as per the wireing diagram says its "feild installed". I keep thinking that since I'm not getting Voltage between Y and C on the board it's a bad board... Any ideas?

Forgot to mention That I'm getting 24v and 120v on the transformer so that looked good.
