Temp gauge needle fluttering

I just purchased my first ever Jeep....87 Wrangler Loredo 4.2 MT. When i got her The only gauge that worked was the speedo. I have all the gauges working now but the temp gauge needle flutters around like crazy. When the engine is at an idle the needle settles down to an accurate reading but as soon as the rpms come up it flutters like crazy. I'm guessing it has to do with the voltage but don't know how to fix it.
