Can you replace the spark plugs on a Jaguar V12?
Please try again later. Replacing the spark plugs on a Jaguar V12 may feel like daunting task but with this easy guide you can do it yourself at home. All you need is some patience and some tools. A few episodes back I picked up a gearbox for my 1966 Jaguar S-type project car however I didn’t get a chance to show it Om film.
Why does my XJS ignition system not work?
It might also struggle around the peak torque point. Although the V12 constant energy ignition module is fairly tolerant (it runs OK with the blanked second coil removed – albeit with a loss of spark energy) the ignition system will behave oddly if the coil is not the correct load match.
Where is the auxiliary coil in the XJ ignition system?
The auxiliary coil, located in front of the radiator, is not a spare or a backup; it is designed into the system for producing a good spark. If either coil goes bad, the performance will suffer. Since mid-1989, XJ-S’s have gone to a Marelli ignition system that also uses two coils.
How many cylinders does a Jaguar V12 have?
The Jaguar V12 H.E. has 12 cylinders, turns at 6500 RPM, and has 11.5:1 compression, making it one of the biggest challenges for an ignition system in production automobiles. To cope with this, Jaguar has incorporated some sophisticated ignition technology.
