stagemaker Posted September 23, 2012 Share Posted September 23, 2012 I have bought my first caterham (thanks to all those who offered advice). When i stop the car and turn the key from the ignition the engine continues for a couple of seconds before turning off. Is this a problem? I have a Rover 1.8 VVC K series.

revilla Posted September 23, 2012 Share Posted September 23, 2012 I can't say for sure that it's normal, but my 1.8K VVC does exactly the same. Maybe not as long as a couple of seconds, but there's definitely a delay between switching off and the engine stopping. I'm sure one of the technical gurus on here will enlighten us as to why it does this? Edited by - revilla on 23 Sep 2012 15:54:37 Link to comment Share on other sites More sharing options...

Area Representative Steve Wright Posted September 23, 2012 Area Representative Share Posted September 23, 2012 They do that if the cooling fan is running at the time. Can't remember why but I think it keeps current going onto the EMS or something like that. Link to comment Share on other sites More sharing options...
john milner Posted September 23, 2012 Share Posted September 23, 2012 This has been covered before so a search should give a better explanation. I can't remember the finer points but when the key is turned off the fan can still be spinning. This generates some electricity like an alternator which gets fed back into the wiring and ends up in the ignition system. It doesn't happen very much with mine in the winter.

stagemaker Posted September 23, 2012 Author Share Posted September 23, 2012 I did a search but it is pretty difficult without a key word. Thanks for the posts so far. At least it tells me I am not to worry. Link to comment Share on other sites More sharing options...
tbird Posted September 23, 2012 Share Posted September 23, 2012 Stagemaker there is a thread here, I am sure there is another but cannot find it at the moment aha found here Tim Edited by - tbird on 23 Sep 2012 17:47:52 Link to comment Share on other sites More sharing options...
revilla Posted September 23, 2012 Share Posted September 23, 2012 Thanks guys for your usual informative explanations! I've read the other threads and it all makes sense, although I never would have though of either possibility myself (the fan acting as a generator or the alternator self-exciting through the warning lamp). I learn something every day. Link to comment Share on other sites More sharing options...

St Eve Posted September 23, 2012 Share Posted September 23, 2012 Quoting Steve Wright: They do that if the cooling fan is running at the time. Mine was the same ("was" because I have sold it and traded up to something else). Startled me at first but then I calmed down as it seemed a consistent feature. What happens when you switch off and the fan is not running? Link to comment Share on other sites More sharing options...

St Eve Posted September 24, 2012 Share Posted September 24, 2012 Quite. My point precisely. So that's all good, then... Link to comment Share on other sites More sharing options...
