2.3L ('83-'97) 89 Ranger 2.3 - oil gauge wacky !

[yeehaw89]

Hi y'all, new here been learning a lot on this site! Question is- my oil gauge is all over the place! Pinned all the way to high then fluctuates all through the very L . A turn signal makes it move !
No sputtering or loss of oil or anything that I can smell. Drives fine. What could it be?

Thank you

A bad ground would be one suspect.

Yep, would suspect a bad ground or power to the dash. The oil gauge "should" just be a dummy where anything over 5psi grounds out the signal wire and the needle goes to the middle.
