Can he also fix a Bosch 1970 W111 wiper motor that doesn't shut off properly
when in low-speed mode? I

I pulled the alternator and will have it tested tomorrow at a local shop. The
guy runs a one man auto electric shop and will even let you come back and watch
the procedure. He will often rebuild them on the spot. New bushings,
electrics, diodes, rectifiers, and all that stuff.

I did that with my 220D alternater. All I got back was the case

I cannot see how a bad diode/Rectifier, loose belt, bad fuse etc can
keep
the light on as you describe.
A bad diode can. The circuit has already been adequately described,
perhaps a bad ASCII schematic?

Wow, the word-wrap really hammered that! Correction
is left as an exercise for the reader... As a hint,
the three ()()()() windings are all the way out at
the right.

Jim; I appreciate this dissertation of the regulator circuitry which I
obviously never fully understod. I am saving it.
Blame it on the military. Unlike others who gained expertice in electronics
and such, I spend a lot of time on KB duty and in the brigg for being non
conforming, contrary and
Thanks to all for your input. I just checked a few more things.
Battery takes a charge with charger.
Car starts with good battery.
Light goes off when car starts.
Light comes on when car is shut off.
Voltage at battery cables with car running and unhooked from battery is
11.1 at idle to 12.2
Bad diode in alternator.

Nope, def'n a loose belt. Go ahead and replace all the belts on the car,
and while you're at it, any rubber hoses or other components. Then and only
then will the light go out. Except you may also need new injectors, and a
headlight switch. But first change the belts.
Or - just change the
Mike:
Your diodes are fried.
Please do not run the alternator without the battery in the circuit, it
will, if working (and your isn't) go way overvoltage and fry things.
Not good. This usually finishes off weak diodes, by the way.
12.1V will not charge the battery, you must get at least

I cannot see how a bad diode/Rectifier, loose belt, bad fuse etc can keep

happens, including the last part. The lamp gets ground from the I wire
only, and only when the alternator charges.
With the key of, do any other

Incorrect, which is why your ign. switch idea is incorrect.
