1988 LSC. My tach works fine unless I turn on the headlights.
With headlights on, the tachometer lamp is dark. The rest of the dash is illuminated as normal.
Also, with the headlights are on, the tach itself doesn't function. The dial indicator stays on zero.
Everything else works.
Turn off headlights and it works again.
I have a feeling there's a problem with the headlight switch, and it may need replacing. But I'm hoping someone has another solution, like a loose wire. I'm far away from home, no shop manuals, no tools. Replacing the switch would be very difficult.
It happened suddenly last week. Nothing was changed, no recent work was done on the car and there are no other problems.
Thanks for any ideas...
