OK, so it worked before my daughter had the timing belts changed and now, it doesn't...anyone have any ideas? On a similar note, the voltmeter works intermittently even with the new alt in it; jumps up and down but alt is putting out good current...getting a little frustrated with her beasty...anyone want a rust free dual range ea82?!? Last question, fuel guage isn't working...checked the sender and it looks like new, no crud or corrosion...thoughts?

Additional information

Loose connection on the back of the instrument cluster? I have some similar issues on a 90 Legacy, gauges drop off, come back on... that's where I was heading to check mine since none of the systems have anything in common other than that connection at the cluster itself.

mine is the tach and fuel gauge.

The tachometer should tie to the minus side of the ignition coil on a yellow wire. Check that connection.

 

For the fuel gauge problem check to see if there is any voltage getting to the black/yellow wire at the sensor with the ignition switch ON. If not, then there is a bad connection to the gauge.
