Oil Pressure gauge - mismatched sender?
I fitted a set of VDO gauges to my car and finally wired them up today. Volts and oil temp seem to be OK, but oil pressure goes off the scale (5 bar) when I start the engine, and stays there. The sender has a separate terminal for a warning light, but that isn't coming on with the ignition.
Does that sound like a 10 bar sender has been supplied, is the sender faulty (big reading and no warning light coming on), or could the gauge itself be faulty? And is there a way to test both?

Thanks guys, it seems that my sender is bollocksed.
Cleaned both terminals and that fixed the light, but made no difference to the gauge.
I earthed the cable and the gauge went to 0, so I put the polarity tester on and found that the sender terminal for the gauge doesn't earth, even if I stick the probe right in the centre.
Now to find a replacement.
