Always happens with plugs and points as the coil is left energised. It doesn't usually affect electronic ignition, but if the coil is storing charge for a long time with nowhere to discharge to it will. I saw one explode and coat the whole under bonnet of a Granada with hot oil, lucky not to go up in flames, because it was the wrong type. There's a lot of wire in them when they gut themselves as well.
