My van died a few days ago. I did the FSM trouble shooting routine and
found a poor ground, a poor coil and a rotor that had no continuity
between the "shutters" and the ground of a frame/battery.

The FSM said to replace the rotor - which I did. The vehicle started
immediately and ran fine. It still starts and runs fine.

What is the purpose of the continuity requirement for those "shutters"
on the rotor and the rest of the frame/ground? I cannot find any
information in the CC FSM, nor on any web sites related to CC products
of the 1984 vintage.

Thanks in advance for ANY info.

I guess I'll try to answer this since nobody else has.
(trying to remember the '79 1.7 rotor)
The shutters would be connected since they are all 4 stamped
from one piece of sheet metal.
I remember there being a grounding tab that hits the top of the
shaft to ground those shutters. I doubt that is to allow them to
work, but instead it is to ground them to prevent spark from getting
into the pickup.
Oh, remembering, I did have to readjust the advance after changing
the rotor (had changed the cap a few days earlier).

I don't know what the requirement is, but when the rotor on my 83 voyager
had an intermittent ground/continuity the engine would NOT start.

I spent a bunch of time doing the trouble shooting routing as shown in the
FSM. I did find a poor coil and a poor ground for "the computer" but the
final detail was the rotor. I bought a new rotor as the FSM said to do, and
the engine started and ran fine (still does). I did not adjust anything on
the distributor on otherwise when I replaced the rotor.

The rotor on my 85 Lebaron broke the locking tab on the rotor and it
just spun loosely so car just conked out. Took me a week to stumble on
the problem but boy that sure was cheap to fix : )
