<VV> 1965 Corvair Gas Tank Ground Wire

[Paul Fox]

 Check the mini wire harness where it plugs into the OP switch and the engine harness. It's often in bad shape. Be sure there is no pipe tape on the threads of the OP switch. The switch itself can be bad also. Check to make sure the bulb is good in the dashboard. Make sure the dash ground is clean. Other than that, the problem may be in the harness itself.Paul Fox

 Gas tank sending unit has nothing to do with the temp/press light.

Have you simply hooked a jumper wire from the terminal of the oil 
pressure switch to engine ground to see if the Temp/Press light comes 
on? If the light comes on with the jumper then it is just a defective 
switch. If the light does not come on, then check the lamp in the gauge 
cluster.

Yes, there can be an open in the dash, body or engine harness, so 
testing either end of this chain gets us to where tests need to be made 
next.

So I made up a new ground (earth) wire, cleaned all the connections and installed it to what I think are the right locations. However this has not corrected the problem and I am now wondering if I might not have not connected the ground wire correctly?
