Ignition light
Turbo Mini Forums

Hi all the orange ignition light sticks on and goes brighter as you press the throttle used to come on and just go off when i drove when the mini was standard any ideas what ive done wrong?

Thats the oil pressure light.

Check that it is connected to the oil pressure switch at the front of the engine.

If it's connected, then you have a big problem. No oil pressure.

Check that your oil pressure relief valve is not stuck open.

i havent run a the wire to the oil pressure switch. i think i mixed the wires up do you know the colours of the oil pressure switch wire and water temp?

Haynes says for Mk4 or 5 models, White/Brown for the oil pressure switch, Green/White for the water temp sensor.

Varies depending on the year.

cheers mate ill go check

on mine 1993 loom i seem to recall oil pressure switch white/brown and temp sender blue/green

no longer a series, but still 1.3 turbo.

Hi,
White with brown stripe for oil press. and green with blue stripe for water temp.
If you've got the central speedo (old type) it sounds to me that you've got the oil pressure warning light in the the hole for the alternator and vice versa.
Meaning your alternator is knackered!
It would need some skill to stretch the oil pressure wiring across the engine to where the temp sender is! LOL

Two wires snapped off when I was taking the engine out I got the green blue wire on the Water temp and The white brown on the oil pressure. The alternator seems to be working fine. Water temp don't work so ive ordered a new switch to try. The oil pressure light just sticks on after I start the car. It was fine in the metro maybe oil pressure valve stuck open Il have to check.

doesn't the metro oil pressure switch work the opposite way to a mini one? might be wrong but sure i read it somewhere.

Hi,
Easiest way to tell what's going on is just take the wire off the switch, and the light will go out. Then hold the wire down to earth and the light should come on. If so it's the switch. You just need the ignition switched on don't start the engine.
