Ammeter not reading zero

[Vinny]

Mine oil was doing the same thing. Turned out to be the sending unit. I bought one at O’Reilly’s and it made it worse. Someone on here recommended a different one that i had to order and it now reads the same as my mechanical oil pressure. That started me on the path of getting all my OE gauges to work correctly. Ended up doing the same with my water temp, and again, sending unit was the culprit.

So, what was the different one that was recommended that gave the good reading?
