Bob .. I've just finished wiring the low voltage lights on both my B&C
alternators.
I used LEDs with a 470 ohm 1/2 watt resister in front of the plus-side per
the manufacturer's instructions to protect the LEDs. However, when the low
voltage condition is gone, the LEDs dim but don't go out completely!! I
thought there was an electrical problem until I realized that the voltage
regulator 'thinks' the lamps are out.
What can I do to completely shut off the LEDs once the voltage regulators
indicate there is no longer an error condition? Is this because they
usually use incandescent lights?
Regards,
David

Thanks everyone for the suggestions. I found a local alternator rebuilder who took
a look at it. Replaced the brushes and that seemed to fix it. Total cost $50.

You might want to check the slip rings on the armature for wear before
investing in a rebuild kit. Sometimes the slip rings are worn to the
point that it makes more sense to let a rebuilder have it than to just
replace the diodes, regulator, and brushes with a parts kit. A good
rebuilder will replace the slip rings. That will also confirm that you
can remove the bolts that hold the case together. Sometimes the bolts
are seized pretty tight but otherwise I have always found parts kits to
be easy to install. Sometimes you have to get creative and use a piece
of string or something to hold the brushes retracted for assembly.
Rebuilders use the part number you mentioned whereas the parts counter
usually wants to know what vehicle it came out of.
