A/C Clutch Coil Resistance
For 1993 Sedan Deville 4.9L:
Does anyone know the nominal spec for the A/C clutch coil resistance?
I'm reading 1.2 ohm which seems rather low.
Any info is greatly appreciated.

Re: A/C Clutch Coil Resistance
Don't have your specific clutch coil here but the one's I have measured from "modern" vehicles have been in the 1 to 2 ohm range. A strong magnetic field is required to "pull-in" and grab that drive pulley.
Once the clutch is engaged, the resistance is increased to produce a "hold-in" level of magnetic field strength.
Sounds like your's is in the normal range to me.
