guage issues

[markbob@ameritech.net]

Hello All....

I have a 69 Coronet with non ralleye dash.....

I checked voltage limiter function at fuel tank sending unit with a test light.....I get a flashing light....

I checked voltage limiter function at temp sending unit with same light....I get nothing....
I placed a jumper wire from sending unit wire to ground.....gauge does not move....

I checked all wires behind dash....especially those leading to the round plug in center of instrument cluster....nothing seems amiss....

I checked wiring diagram....and the temp gauge and fuel gauge share feed from voltage limiter....

How is the cluster grounded? Is it through the dash itself? My headlights, instrument cluster lights, emergency flashers all work.
My steering wheel is not installed, so the harness connections to that are not hooked up....

Any thoughts?

thanks,

Mark
