[DML] Re: Alternator Sound

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

Other things that can cause the alternator to not "put out" at low RPM's:
Wrong bulb in the dash
A high resistance in either the output wire to the battery or the dash
light
Too small a pulley on the alternator
Slipping belt
A problem inside the alternator, bad regulator or diodes.
This *might* be normal if you have too big a load on the alternator at
idle like a very low battery, lights on, A/C running, etc. Go to Sears
or someplace like it where they will do a free check on you battery,
starting system, and charging system. Or you can take you alternator
off and most places that work on alternators will bench it for free.
Have the battery load tested too. Turn the key on but don't start the
motor. The battery light should light. This is a test of the
alternator AND the warning/charging circuit.
