Thanks! I have seen those schematics but didn't have a copy. Sloane, I
think you are right. The stalk switches and horn relay are likely culprits.
The kinds of quieky electrical problems that Mr. Guzman is addressing often
stem from broken grounds but a short in the stalk switches may eventually
be found. (Assumption that 'A.' is male, thus the prefix 'Mr.'. Although
today, assuming a gender is PC suicide.) Anyway...
Good words of caution about un-fused circuits. I once saw an interesting
gadget. It was a fuse holder, with a 20A fuse installed, and clip lead on
one end and a battery terminal connector on the other. The idea is to
remove the negative battery lead, attach the clip to the cable and place
the other on the battery post. Any circuit except the starter could work
but an accidental short circuit would pop the fuse rather than burning the
harness - or worse.
From the pictures that A. sent, it would be good maintenance to
disconnect the battery and un-mount the relays for cleaning. As we know,
the lower relay is the starter relay. It keeps starter solenoid current
from the ignition switch and helps provide the seat belt starter interlock.
A. also notes that the upper relay, the horn relay, shows a lot of
corrosion and that he has a new one on order. Great opportunity to clean
all the wires and Lucar connectors and verify that they still fit securely
on to the 1/4" male tabs. If not, replace them. I use SimpleGreen for
cleaning followed by brake cleaner as needed.
A. also reports that although the horn relay 'clicks' at the press of
the horn push, the horns do not sound. This again suggests a bad horn
relay. Although why the headlights flash on is more likely to be a short in
the column or associated stalk switches. Testing continues...
