As Ed says grounds are very important on electric gauges. DO NOT sister the grounds together under the dash for the temp gauge run a seperate ground for that gauge to a good ground. Also i dont like the idea of the sender in cyl head(if thats were yours is) i like it up in the intake were it belongs,with header heat not effecting your readings. Go see if a friend has a mech gauge you can use and check it against your electric. Pressure test the cooling system first and find the leak cause if you have a crack or gasket problem the temp gauge problem dont matter anyway its got to come apart.
