5ktq electrical problems update (not fixed)

[Eric_R_Kissell at whirlpool.com]

Where are you measuring your voltage?  12.8v should be plenty to run
rather normally.

My BTDT says my 1989 200q Avant and my 1986 5000cstq run OK below 12v.  I
think it had to get below 11v down towards 10v before I noticed a problem
when my system was not charging properly. BTDT two or three times.

If you are really seeing a problem with missing when you go below 12.8v,
then I would think you might have a high resistance in the wiring for the
ECU or the ignition system that makes 12.8v much less than that when it
gets to the affected systems.

Your charging system might be fine.  I would guess that it is not too bad
because 12.8v seems plenty to me.

Check all of your grounds at the several places where the ground
connections exist.

Again, can you explain where you are measuring 12.8v?
