Previous owner installed tach and small clock in dash. since ive had it, (6 months) everything was working fine electrically, until about 2 weeks ago.
Now:
- the instrument cluster light on the left is not working
- the left turn signal light stays illuminated, but blinks when signaling left
- taillight operates fine, as do both blinkers
- small clock does not receive any power
- tach still operates, but barely
- this only occurs when the headlights are turned on. if they are off, blinker works fine, tach reads normally, instrument cluster light works, and small clock runs and lights.

Im no Edison here. I do have a voltmeter and a Bentley guide to check some stuff if need be.

Thoughts?

THANKS!
