a/c help!!!! New contactor wont engage......

[xcrider76]

bought new capacitors and new contactor and new fuse for thermestate and contactor still wont engage by itself. If i push it manually it does come on but wont stay.

what does the contactor control? fan or compressor...
control voltage should be around 24 volts. did you take the old one to match the new one to?

Can you send me a picture of the wiring schematic or ladder diagram? I'll tell you how to wire it.

The compressor. But i found the problem. The yellow wire and a light blue wire loss connection with one another.
Thank you for responding though.
