I just installed a new VDO oil pressure gauge #350-104 80 psi & VDO # 360- 006 10-180 ohm 80psi pressure sensor. I hooked up the "+" side of the gauge to the same power supply that illuminates the gauge pod lights. I wired up the gauge "S" labeled side to the "G" on the sensor. I ensured that the sensor threads were clean during install on the engine, hopefully to ensure a good sensor ground. My problem is that as soon as I turn my ignition to "on", the needle on the pressure gauge goes off scale on the high side. With the engine running, and showing a false high off scale, If I remove the ground from the gauge, the needle drops down below the zero side. I have checked that all the leads contacts are tight. The only thing I haven't done is run an ohms continuity check on the G wire. Any suggestions on solving my issue?
