Alternator Not Charging and Charge Lamp is Out

[Shin Hoshikawa]

Ed:

I remember reading an article about the Audi's charging circuit, indicating
that a positive power wiring goes to the alternator to get it charging, and
a charge lamp sits in-between that particular wiring.  If a charge lamp is
out, +12v wont' get to the alternator. If so, the alternator won't charge
even if it is perfectly okay.  I'm not sure if this applies to your case,
but I think it's worth thinking about it.

Regulator slip ring brushes?

A dead bulb in the battery light socket of the instrument cluster will
prevent the exciter wire from working, according to Scott Mockry's wonderful
website.? So will corrosion on/in the wire.? I've had to replace that wire
from the starter to almost the spot it comes through the firewall because of
internal corrosion on the wire strands inside the insulation.? I've read of
folks having to go all the way to the fuse box.

I posted about this briefly several days ago in relation to an ignition
switch thread... I have a no-charge situation.  I checked the obvious and
then hit the Bentley.  I seem to have a problem with the exciter circuit.
Connections and belt were all tight and good.

Exciter circuit amperage was around 20 when spec is 150-185.

When I turn on the ignition, the battery light does not come on.  The
antilock light does but goes out almost immediately.

Bentley points to IC or exciter wire between alternator and IC.

237k on the clock.

Any ideas or helpful hints?

Thanks,
Ed
