I recently purchased a 1993 Land Crusier with a nonworking oil pressure gauge. I bye-passed the wiring harness and directly grounded the sending unit wire and the gauge began to climb. I then ran the engine and with this same terminal wired directly to the sending unit; upon starting the engine the gauge began to climb; it appears both the sending unit and gauge work. However, if I bypass the "condenser" (part number: 86516-90k01) within the oil pressure sending wire harness the gauge will seemingly want to read 100%. It seems that the "condenser" is needed to regulate the DC signal to the gauge. In testing the "condenser" it has zero continuity but reads out with a light indication under Mili-Ohms. Curious if the "condenser" should have continuity? Any direction on all of this would be greatly appreciated!
