My fuel gauge stays on full never moves, temp gauge doesnt move at all,speedo and volt and oil gauge works fine.All gauges are electric, I checked the fuse, looks good. I didnt wire this car its got an EZ wire system and the guy that did the wiring did a nice job everything looks neat and all so If anyone has some ideas Im all ears, Thanks,

I would check the grounds to the dash. Those gauges may not be grounded properly

Ok I'll take a look at that, thanks

You didn't mention what vehicle. The 60's Fords used a 5 volt instrument panel voltage regulator for the temp and fuel gauge. When it goes bad your gauges will not work.

Sorry Bruce, My car is a 34 chevy streetrod, the electrical system has been updated to a 12 v and the gauges are Classics from American. That is interesting about the fords,I didnt know that, thanks,

Wow that's something,I wounder if I should just find a new sending unit that is matched with a new gauge, I wanted to replace the gauges with stewart warner ones but i'll try running a ground wire to the dash like you did and see what happens, anyway thnks your info gives me something to work with,

I had a similar frustrating problem with my Classic gauges on a new install. Classic has a great tech line. I could not figure it out since I wired the car and have done it a lot of times.
Turned out to be a bad ground. I re-did starter, gauges and charging system with star washers and problem solved.
