die when the headlights were turned on. Someone mentioned that the tach
was looking for a ground through the light wiring for the instrument.
That turned out to be true, somewhat. To test this I pulled the
instrument to inspect the wiring and found what you see in the picture.
One arrow points to the ground connection on the back of the case and
the other arrow points to a common ground just floating around behind
the instrument. For an experiment I slipped the ground wire connector
over the threaded mouting stud of the case back and shoved the tach back
into place temporarily to find out about the missing ground theory. It
worked! You didn't think it was going to be that easy did you? The
light had not illuminated the instrument before either, so after
scraping and sanding the bulb hlder and the tube fitting on the back of
the tach that the bulb shoves into, the light worked too, but wait
there's more! After this hollow victory I had to use the horn on the
test drive. Now the horn does not work, but when I push on the steering
wheel stalk to activate the horn, the brake warning light comes on. I
just love electrical problems. Not in my element here. Any ideas?</div>Mike MacLean</div><div><br clear="none"></div></div></div></div>_______________________________________________<br clear="none">
