class=3D"">In an earlier post I told how my tach in my 69 GT would die =
when the headlights were turned on.&nbsp; Someone mentioned that the =
tach was looking for a ground through the light wiring for the =
instrument.&nbsp; That turned out to be true, somewhat.&nbsp; To test =
this I pulled the instrument to inspect the wiring and found what you =
see in the picture.&nbsp; 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.&nbsp; 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.&nbsp; It worked!&nbsp; You didn't think it =
was going to be that easy did you?&nbsp; 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!&nbsp; After this =
hollow victory I had to use the horn on the test drive.&nbsp; 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.&nbsp; I just love =
electrical problems.&nbsp; Not in my element here.&nbsp; Any ideas?<o:p =
