now, now, it's running isn't it?
leon the coils are generally located under the tank.
You'll find points or pulse coils usually on the right side of the engine under a smallish round cover.
If it's cdi (capacitor discharge ignition) the pulse coils will connect to an igniter or cdi which then tell your coils to fire.
can't remember the set up with points, my memory is hazy.
so this replaces the points, distributor, coil setup, of the car.
it's basically the same setup but wired differently.
you'll also find two carburettors under there instead of one but that's a sore point at the moment so we won't go there.
