So, I've been trying to install an external condenser to my 1985 Puch Maxi according to the following link:

Only, it won't work. If I install the condenser internally in the place where the old one was, it works. Only, it's longer than the old one, so it sticks up to close to the flywheel allowing the flywheel to shred the wires. So, I dare say, it works, yes. But, it won't work for more than five minutes before the flywheel boors through one of the wires.

What do I do???
