The older engines only had one wire and the new engines now have 3 wires (black, white and red). The black is cut off and appears they are only using the Red and White. The wiring diagrams I have do not show how to wire the new 2 wire set up to the oil pressure gage. I could guess at it but prefer not to. If I had to guess, red would go to the "S" post and the white would be added to the "-" gnd post. Has anyone else encountered this? Thanks Mike H Read this topic online here: http://forums.matronics.com/viewtopic.php?p=241483#241483 ________________________________ Message 2 _____________________________________ Time: 12:52:16 PM PST US From: david park Subject: RE: RotaxEngines-List: Wiring 912 ULS oil pressure sensor Mike=2C Rotax apparently no longer use the old VDO sender and now use a Honeywell s ender with red/white/black - not used/shield. I have bought a UMA 1 1/4" gauge to match sender. White - signal/ Red - 14 volts/ Shield - to ground at the gauge. Waiting for fuselage coming back from spraying!!!!! to fit!!!!
