ignition coil

Does anyone know if the ignition coil on a 1.0 swift and the one on the gti the same or how do you tell a coil is nackered, power goin in an all but no spark, does the plug below the coil have somthing to do with the spark aswell,

i got a spare 1L coil and it looks completely different dont no about the operation tho.

Look in the manual for ignition system (page 219, section 6F)
u can test the coil with a multimeter (p222,6F-10)
