Clutchless compressors

#1
Hi Good morning and merry Christmas to all. I a usually repair my car but this problem is too confusing for me. I replace my compressor cause thing next to the pulley is not rotating. There is a 12v supply in the compressor. But after I replace the compressor and evacuate the system and add 134 it wont suck. Check voltage again it's only 2.76 volts. No blown fuses. May be its a safety feature that it won't turn on if 134 is empty. Can I directly supply a 12v from battery to the a/c compressor so that |I can add a 134?
It's 2010 corolla.
