1593.0. "Oil Pressure Guage wiring ??" by YUPPY::MCINTYRE () Wed Oct 30 1991 16:35

    
    Can someone out there help me to wire up an Oil pressure guage to my
    Rover V8.
    
    I have had a go but don't seem to have got it right.
    
    The rear of the guage has three terminals
    
    The left and centre terminals are connected via a resistor.
    The centre and right terminals are connected via a hard link.
    
    There appears to be two coils in the dial, one of which might be wired
    in parallel with the resistor. 
    
    I think I need:
    
    +12v
    Earth 
    and a feed from the sender ??
    
    Where do the wires go ?
    
    How can I test the dial to see if it works ?
    
    Any help much appreciated.
    
    
    Regards

    	How about connecting the sender to the engine in a car that is
    currently working and known to be good. Replace, say the oil pressure
    switch with the sender. You may need some adaptors from a shop that
    sells hydraulic supplies to do this. Try measuring the resistance
    from the sender to ground with the engine stopped and running, then
    compare this with the resistances across the three terminals of your
    gauge. This may give you the clues you need to decide what goes where,
    but if not try connecting them in different combinations until you get
    something that works. The resistance measurements should allow you to
    avoid direct shorts, or anything else nasty. The oil pressure gauge
    should be connected to it's regulator , if used to give true readings.
1593.2Use US spec MGB wiring schemeHLFS00::DULK_HFri Nov 15 1991 13:537
    Try looking in the USA spec. MGB wiring scheme.
    Mine has a good working example.
    Similar devices used in Jaguar.
