Thread: Disco S1 3.9 Petrol - Stops and Wont Restart

Hi all , Seeking advice on what to do for the old famous security feature based shutdown problem for a 97 disco.Heres where we are up to - security system cuts off feed to ignition coil -disable feature , when this happens : no amount of alarm system resetting works.All the standard items of other areas have been cleared.My problem : specifically I cant get a wiring schematic showing the alarm system components , and how the coil supply intergrates.I know that theres 2 black boxes involved, door switches for the central locking module , the alarm system itself , key and transponder etc.I just dont want to take the whole thing apart to map out all the wiring ?.I know this has happened before and others have got it sorted out.For me , I just dont view it as an option : committing over 1k in cash to paying out for a new black box system as per rovers pricing.We have fitted a temporary kill switch setup that supplies the coil and beats the stupid thing , but ultimately I need to isolate and replace the at fault parts.Can anyone assist with thoughts , past experience , or suggestions on where to get a full wiring schematic.

Thanks Landover and bacicat2000 , I have already confirmed that the spider bypass plug is fitted in the loom.( Had to do that years ago , when the first starter motor failed...) But you raise a good point , I have read on the american forums of the pins getting corrosion / heat effected and giving poor contact.( Wont I look like a right chump if you guys are on the hammer , and the darn thing has just come loose ...Job for next weekend).Hee Hee - its good to have SOME possible solutions.
Again thanks - will post back if it was loose or in poor condition.
