Many years ago, a friend had an MGB. The trafficator lever was a little =
balky, so we sprayed some contact cleaner into it and the radio quit =
working. Then the panel light dimmer let smoke out. =20

In an earlier post to another list (MGs) I told how my tach in my 69 GT =
would 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?
