I was moving the Escort around today after its drive to Sydney on the weekend. The red oil light stayed on after starting. I checked the oil, plenty in there. Shining a torch into the filler and there was oil up the top. The switch was still plugged in.

Could it just be a problem with the pressure switch, or could is the pump on the way out, or maybe something else completely?

Oil pressure is the yellow light.
red is the alternator light, check the push on terminal at the back of the alternator, hopefully thats it, not the best design.

My oil light came on the other week, somehow the shielding for the cable had rubbed onto something and shorted its self...... on a Mark II but cant help to check....

you can fit a gadge as well a light use brake line and fittings get the rishe fitting for the block as its crack prone ot make the rigth one
