couple guage electrical questions

I am sure you have gas in it, and you have check for contanuity from tank to your guage.It could be your guage in your dash.
It consern's me about your bulb's being loose becaus when you turn your key on the power to the guages cold be toutching another curcit.
Make sure your dash is gronded good, If it need's a ground ,It can pull it throuw a bad light bulb, Get the lights in the dash away from the dash and see if you have a good ground if you do try to wiggle it and see if you lose your ground

Hope I have not confused you my spelling is getting better but still not perfect :coffee2:
