I recently replaced my instrument panel with the upgraded one with the tach and guages. Almost everything works but the oil pressure guage. I did replace the sending unit with the guage type sender, and was careful to disconnect it before hooking up the new panel. I do have a multimeter and would like to know if someone can give me the values I should be reading from the sending unit. It was a used one and not sure if it is good. TIA Roy

Hand me that crowbar.
