Battery light is coming on?

Hi,

No, it is not a shim. The damper and the pulley should be in 1 complete piece.

Too bad after replacing the alternator and the AC still don't work. Btw is the alternator working well now?

Guess you need to fork out more $$$ for the AC coil or compressor whichever is at fault.

Hi,

From what you described, probably the magnetic clutch contact was worn so it was refaced a shim was needed to keep the specified clearance.

By adding too thick a shim, the clutch was too far away to be attracted by the coil so they readjusted by replacing with a thinner shim.

It sounds like the compressor is causing the belt to slip. You need to have it diagnosed correctly to determine if it's a problem with the belt or the A/C system. The compressor isn't necessarily the only part of the A/C that could cause that.

Hi again

Glad that I have been of help.

Chicken or egg is true.

The clutch locks when the compressor is required to work and unlocks when the desired cooling temp is attained or during hard acceleration.

When the clutch engages, it tends to slip before it fully engages and over a long period of time, the wear will create a bigger clearance gap between the plates. This will result in in partial engagement of the clutch and heats builds up when slippage occurs. This will fry the coil.

Fixing the clutch might have protected the coil but then again it could have been the other way round. The strength of the coil diminishes due to old age, poor wire connector contact or oil getting between the coil slowly shorting it. This will cause improper clutch contact.

The alternator failure should be just coincidence because even if the coil is shorted, the fuse will blow protecting the alternator, unless you have installed very high amp fuse which will cause the alternator to give way before the fuse blows.

Just remembered, maybe the alternator was not producing enough current so the coil got affected.

Most of them. It needs to be diagnosed professionally.

Even if related, the damage to the alternator might only slowly build up until it gives way thus the delay.

If the battery is ok, there is no need for it to be replaced.

The new alternator will charge it back after some running of the engine.

With the light coming on and others dimming, this is not a dummy reporting. I suspect one of two things. First let me ask if it occurs often and if not does it appear to be happening more often? Any predictablility on the occurances? Such as colder weather, etc.

The first thing I would look at are the connections.

Then, even though the alternator tests good at Autozone, you might still suspect the alternator as the culprit. Was the alternator used, rebuilt or new?
I have had better luck with used alternators and new than I have with rebuilt ones.

You are welcomed.

Glad that we have been of assistance.

Happy motoring.

Check the alternator belt tension-if okay get the battery and the alternator load tested.

Too look for a short in the electrical system do below
