Southern, CT. Far far away from most of you West Coasters! (you're one
of those folks, right?

Well, actually, Mr. Brian Honnold and I came to a new conclusion that
would lead to the fixing of my car. It would be a grand xmas present.

1981 Scirocco turned CIS-E 16v 1.8l.

Bottom line: I'm getting no spark, BUT voltage at the coil. Coil's good, 
distributor's good, and hall sender is good.

The negative leads to the coil... one of them go to the hall sender
computer which ordinarily supplies the temporary pulsed ground signal to 
complete the circuit that makes the spark, right? The other wire (a 
red/black) wire goes into the fuse box at C19. That curcuit goes to the fuel 
pump relay (grounding the solenoid of the relay), as well as the tach and a 
couple other devices.

I know the fuel pump relay works, but could the tach being fried or
something make a constant ground to the coil which would cause no
sparky???

I went outside this morning (coooold!) about an hour ago to see if I could 
figger anything out with this whole dealy... The object was for me to bypass 
any circuitry that may head off in the area of the tach.

So, I cut the red/black wire at the coil terminal 1. Now, I had to find a 
good ground (right?) for the fuel pump relay.

Mr. Honnold (yes, he deserves being called Mr. with all the crap he's helped 
me through) suggested I connect terminal 10 on the knock box to the wire I 
cut, but that doesn't seem to do anything. I see in the Jetta's Bentley 
wiring diagram ('89 CIS-E 16v) that terminal 10 on the knock box does in 
fact go directly into the fuel pump relay solenoid, so I tried that.. No 
dice.

I'd like to know why the fuel pump relay solenoid gets its power from the 
source it does: positive comes from terminal 15 inside the fuse box 
(normal), and the negative from terminal 1 of the coil (???). Why here and 
not just chassis or battery ground? Rev limiter? My '81 had a rev limiter?

Inquiring minds want to know.

This would be a BITCHEN xmas present if my rocco ran!
