Well, since 1978 the SAAB CIS has Lambda feedback with O2 sensor and
electric mixture control. And

Of course it is. Do you want one velcro'd to the dash

I put a volt meter, ammeter and oil temp gauges on my 200D. That told me
most of the missing pieces. Between oil pressure and temp, I could tell
when the oil was a little low.

The brushes were worn, and one was shorter than the other. Idiot light
works fine, but did not indicate a failure. I replaced the brushes

The output of your alternator was not zero, but it was clearly not
up to the task of running the car. The alternator

Or an open rectifier or open rotary coil -- all will cause zero output.
You should get the lamp on if you have current draw through the field
(rotary) coil, so no glow on the dash would mean no current draw.
It's fairly common for an alternator failure to not turn the dash light
on.

It often won't. That light, while an extremely elegant bit of
1940's (?) engineering, is a bit past its prime as a diagnostic aid.
With a tiny bit of circuitry the light could still be there but
it could catch a lot more. DC voltage, AC ripp
and the idiot light itself.

Just went out and checked. All the idiot lights come on, including the

I think I am going to stick with my original suspicion, of a massive
regulator meltdown or broken brush.

One of the things I love about older MB diesels is the mechanical FI and
