A Dissected Ignition Coil

?
Coils are a disposable part when they begin leaking or are burnt up.
Same goes for ignition control box's, electronic voltage regulators and ballast resistors.
Non rebuildable.
Keep spares of these items to swap out when needed and don't bother yourself with the mess of taking them apart.
Does seems a waste though, they should have made the parts more serviceable like in earlier
days. 40s and 50s cars were not built with so many disposable parts.
