RE: IML: a/c in 57 imperial

["Dick Benjamin" <dickb@xxxxxxxxx>]

In some years, the clutch coils have a separate grounding wire, either
soldered to the outer metal case of the clutch unit or connected to a ring
lug which is grounded to the compressor body.  When you check your coil for
continuity, as has already been suggested, make sure that you get continuity
all the way back to the battery negative post.  If you don't investigate the
grounding wire before deciding the clutch coil is bad.

The first thing I'd check would be continuity through the clutch coil.  An
ohm meter should show just a few ohms of resistance in the coil (almost a
dead short).  If the coil is open the clutch will not energize.  If it was
shorted you'd blow fuses.  But you say there's voltage present so that tells
me no blown fuses.

It has been eons since I've had one of those apart, (I've killed a lot of
brain cells over the years) but I believe it's a pretty simple task to pull
the clutch and coil assembly off the compressor and replace them.  You'll
need the proper puller to remove and replace the assembly.  Also a set of
feeler gauges to adjust the clutch travel.

Good luck.

hello america
i recently  posed a question about the a/c operation in our 57 imperial :  
it was about the magnetic clutch not tuning after the clutch  has clicked in

the clutch it will not click in  when the ignition key  is turn on

.
