Hi All,
You may remember my recent problem with what ended up being a short in
my GP Wiring Harness. I don't recall where the story left off, but
the Indy who said they could work on it but ended up not being able to
fix it even though I was telling them what to do. Anyway, my wife & I
went to the Indy last Thurs. and after cranking for 20 seconds, then
waiting for 30 sec my wife got the car to start on a 80F day on the
2nd starter cranking.
My wife drove it home and we finally started on it this AM around
9AM. My wife was a big help as I can't stand for very long at a time,
so I mostly "Supervised" (my preferred mode of operation) as she
removed the linkages, the manifold bolts and all the bits and pieces.
After lifting the Intake Manifold off, we were able to examine the GP
Wire Harness. We found the wire going to GP #2 had lost its
insulation. I don't know if it was abraded or perhaps the heat cycles
made it brittle, but the insulation was gone from the point where the
#2 GP wire left the main harness and went to the GP. Rather than
re-wiring the harness completely as I had planned, I decided to put
some black electrician's tape on it then covered that with the
Universal Magic Repair of Duct Tape to make sure the Electrician's
Tape stayed in place. Also, before putting the Electrician's Tape in
place, I cleaned the bare copper wire with Brake Cleaner because the
copper wire was coated with black diesel oil which prevented the tape
from sticking.
Then, as we finished everything up, I found the mandatory error which
seems to appear in all my repairs - the Accelerator Linkage that
attaches to the aft end of the linkage near the firewall was on the
wrong side of the GP Harness! I had it on the inside, between the
harness and the cyl head, and it needs to be on the outside. As it
was I was prevented from snapping it in place. (This is when I said
DAMN!) So we decided to stop at that point, I was beat and so was my
wife, who had stretched the tendons of her legs when leaning over the
engine to reach the fasteners.
But we tried it, and it started instantly like it always does,
confirming we had put the Manifold and harness on correctly and that
we had found and repaired the problem. Smiles all around. Tomorrow I
plan to either pop that linkage off at the bottom, or even easier,
unfasten #5 and perhaps #4 GP Wire and move the linkage rod into the
correct position.
On the road again!
