Hello!

Can anyone tell me - is there a diode or diode with fuse, or diode with resistor parallel connected to coil in ac compressor clutch? Car is Stilo MultiWagon 1.9jtd 115 2005 ?

Is it possible to damage coil (make short circuit in diode) when connecting clutch inverted polarization?

What is right resistance of coil? My was 3Ohm, and clutch work fine when I jumped relay, but after my "ac specialist" connected external power to clutch it wont work, my fuse burn and I have 0Ohm - I suspect him - he could connect inversly.

Forgive me my language - I am writing from Poland.
