Ok, so that should have nothing to do with the charging system or battery. The ignition wiring is independent of these.
It could be either the high voltage coil on the stator which powers the ignition, or it could be the timing pickup which tells the ignition when to fire. The timing pickup is usually replaced with the stator so it could be either.
In this picture the pickup is the plastic bit on the lower right with the blue and green wires going to it.
A resistance test should tell you which one is bad. I don't have a manual so can't tell you what the exact values should be. Sometimes when either part fails it will start failing when hot and work again when it cools off, then fail more often until it never works.
