Bradley,

    I just went through this on my 84. Remove the black plastic top by
gently lifting the edges going round it until it's off. Remove the plug from
the ECM. Then put a OHM meter across pins 15 & 19 of the plug from the ECM,
I cut small strips of copper and inserted them into the plug to hook the
meter to. At rest mine read about 500 ohms. I then rotated the wiper by
moving the tab on the opposite side of the arm. As I rotated it, the
resistance rose until about 900 ohms then it went sky high then settled in
again about 1100 ohms and continued to rise. I knew that the dead spot was
my problem. I had cleaned it several time with no luck. I then was
determined to fix it or brake it trying. I sprayed some electronic cleaner
on a clean cotton rag. There is just a little room to clean so I moved the
wiper as I rubbed hard the area behind it as I moved it. I then had to
correct adjustments I made to get around the problem. Be careful not to bend
the or mess up the wiper. Use RTV to reseal the lid as you don't want it
getting wet or dirty in there. Mine now runs perfectly, I could not find
anything in the archives on how to tell if it was the problem and needed
cleaning and the Bentley is not much help on this one.

Joe
