Scirocco-l Digest, Vol 16, Issue 68 (Gauges)

> Ammeter, you can tell if the Alt is charging correctly or not. The needle is centered at 0. When you turn the key or put on a load it swings to the left. When charging while the engine is on, it swings to the right.

Ah, that makes sense now.  I have an ammeter gauge that I pulled at a
junk yard but wasn't sure how to hook it up because ammeters have to
go in series.  Surely I couldn't run the car's main power through it,
but I figured about the best usage of it would be to monitor some
arbitrary system like the headlights or something.

But where exactly do you hook it up?  I'm assuming the blue exciter
wire, right?  Cause I know that's what causes the alternator light on
the dash to work...

> Vacumn shows the manifold air pressure. Are you using a lot of fuel or running economically (or have a leak in the 25 YO rubber).

My BMW has this and literally labels it a "MPG" gauge.  It's one of
those things that's just kinda interesting to watch.  I think I have
one for my scirocco that I'm going to install if I ever get around to
working on the car and not just school stuff :-/
