Grounded lead or bad guage?


Recommended Posts

Symptoms: 1985 Brat - Oil pressure dash guage reads near 75 psi all the time, hot, cold, idling, normal driving, even when the engine is shut off.

 

Measures taken so far yielding no changes: completely rebuilt the oil pump (new o-rings, shimmed the spring, new mounting gasket, etc.)

 

Installed new sending unit.

 

Most likely culprit is....................._______________?

 

If its the wire lead wear are they prone to have problems?

Disconnect the wire and see if it goes to zero.nipper

 

Disconnected it from the s/u. Guage stayed in same place, just below 75 psi. Sending unit is brand new NAPA.

 

Next place to look?
