replaced AC compressor,dryer,ect, & the unit cools, but it seem like the clutch kicks on when the compressor kicks off / or just the opposite of how it is supposed to work. What's up with this?

The clutch can't kick on when the compressor turns off because the clutch turns the compressor on. The high pressure switch or the low pressure switch can make the compressor turn off if you have too much or too little freon in the system. If you're system is cooling you've done a good job with everything right.
