Nev Posted October 6, 2008 Share Posted October 6, 2008 My engine still runs and the ignition lights stay on even when the keys are removed does anybody have any ideas as to what is causing this to happen. I have a 1982 series 3 lwb with a defender ignition. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 6, 2008 Share Posted October 6, 2008 I have a 1982 series 3 lwb with a defender ignition. A Defender ignition what? Key? System? Could be a dodgy ignition barrel. Quote Link to comment Share on other sites More sharing options...
sotal Posted October 6, 2008 Share Posted October 6, 2008 Doesn't every series? What engine have you got? If it's a standard series engine then it will have a manual pull stop, where you pull a cable and it in turn stops the fuel flow in the pump. A later defender ignition probably uses an electronic stop solenoid to cut the fuel which wouldn't be compatible on a series engine. Easiest and cheapest option would be to buy a series ignition with the stop cable Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 6, 2008 Share Posted October 6, 2008 I believe only diesels have pull stop, since petrol engines will stop when you remove power to the ignition. Quote Link to comment Share on other sites More sharing options...
Max Series-3 Posted October 6, 2008 Share Posted October 6, 2008 Mine still runs when i remove the key so must be all series or a common problem (i have a series 3 petrol) Max Quote Link to comment Share on other sites More sharing options...
sotal Posted October 6, 2008 Share Posted October 6, 2008 I believe only diesels have pull stop, since petrol engines will stop when you remove power to the ignition. Very true - Just presumed it was a diesel from the fact that it kept running. Having re-read it - the poster doesn't state diesel or petrol so I guess we'll have to wait and see Just looked and found another post with his reg shown which the DVLA lookup shows it is a petrol 2.25. So I'm only guessing as I've never seen one, but couldn't you just run a switch in the low tension side of the circuit and cut power to the electrics? As FridgeFreezer states it's probably a faulty ignition switch or it's not wired up properly Quote Link to comment Share on other sites More sharing options...

Err, you could, but I fail to see how that's any less time, money, or effort than just replacing the easy-to-get-at-and-not-expensive-to-buy ignition switch Paddocks website has them from a whopping £9.10 to a massive £15 (Note you want the switch only, not the keys & barrel which is £66) Quote Link to comment Share on other sites More sharing options...
sotal Posted October 6, 2008 Share Posted October 6, 2008 ^^^ There you go a nice easy answer Quote Link to comment Share on other sites More sharing options...
Nev Posted October 6, 2008 Author Share Posted October 6, 2008 Sorry had to pop out for a bit. To confirm it is a 2.25 petrol and is fitted with a defender ignition. Looked at paddock spares and was surprised at the price for a series ignition £66 are they having a laugh. Anyhoo have got a spare defender ignition and will fit that tomorrow and see if thats the problem. Also disconnected the battery with the ignition off and the engine is still running does that mean anything at all. Thanks for all your replys much appreciated.

FridgeFreezer Posted October 6, 2008 Share Posted October 6, 2008 Looked at paddock spares and was surprised at the price for a series ignition £66 are they having a laugh. That's the ignition barrel, not the switch that clips to the back. Paddocks do 551508, which is a complete ignition switch according to the S3 parts book, or there's 579085 which looks like the version that works with the steering column lock. Neither are expensive. Also disconnected the battery with the ignition off and the engine is still running does that mean anything at all. Yes, it means you risk b*ggering up your alternator The car will still run with no battery because the alternator is still turning so it's still generating electricity.
