The car is from California so it is _possible_ it came with electronic
Ignician. I am of the remebering that it started with model year 80 but
both Cali & Sciroccos lead the way for 'improvments' so, maybe.

Well, OK. It was diagnosed but what are the symptoms?

Ah, OK. Tach is eratic? Does the motor follw suit or is it a false
reading, this needle jumping up and down? Electrical power to the tach
might involve the voltage reduction on the back of the Inst cluster.
Then again it might involve the main 12v as well. 

This guy needs a cheap Radio Shack meter ~$10. I can dig up some tests
for basic trouble shooting but am limited to Haynes right now, otherwise
I only have half a Bentley to contend with, the back half. (schematics!)

Is the _pump_ getting 12v?

Is the COIL getting 12v?

I'm CC'ing the list on purpose. Feedback will remove scirocco.org from
the TO: line.
