oil guage quit
 

I pulled the instrument panel to fix a faulty trip counter. When I put everything back together eveything works but my oil guage. It's completely dead and worked fine before I removed it. I double checked all wires and even did some wiggling tocheck for a bad wire. As I was putting the panel back in it jumped to life then quit. I moved and pulled wires for a while with the panel out but nothing. It will work if I get the panel part way in but then stop. Any ideas?

Look to the back of the circuitboard where the actual gauge mounts. Check to see if the screws mounting the gauge to the printed circuit are tight. Maybe loosen them ad retighten.

tightening the screws on the curcuit board didn't help. It still does the same thing, when I try and push the intrument panel in, it starts to work, I guess its a bad wire. If all other guages work I'm thinking the sending wire from the engine. The CD manual isn't very clear. Any help in identifying which wire would be helpful.
thanks
