My daily driver has started doing something strange. If the car is running, with the lights on, and I turn the ignition off, the car keeps running, until you turn the lights off, when it then stops.

With the lights off it stops as normal.

It's a 1996 Opel/Vauxhaul GSI - 1800 single cam fuel injected.

I haven't had a look yet, but maybe someone has a clue for me?

has it got a diode thats leaking power back to the ignition circuit

What he said probably.

What they said... probably.

Have you changed bulbs latlely?

I'd also reckon a power leak to keep the ignition circuit live.

Yep.....beleive it or not a faulty light bulb can cause this! along with bad rectifier circuit (alternator) or bad hazard switch

Arrrrrgh

It's the ash, it's the ash, it's coming

My Mk2 Golf would do a similar thing, if you had side lights & an indicator on you could take the keys out & leave it running.
The ignition switch went wrong a while after I noticed it & after a new switch was fitted it stopped it.

Some of the vauxhalls of that era used to have a dim dip relay that caused exactly that. Cant remember which model, poss cavalier but it was in the offside kick panel.

Thanks for all the reponses Guys
