Out of order

'71 VW 1302 Super Beetle fell into out of order this morning.
The cause of motor stopping must be in ignition system.
Ignition coil is 40 years old, though almost of the system had been replaced, the distributor and the high tension cords had been done.
Miserable my Beetle is now left on the way, calling police to tell the mechanical disorder.
Too much humidity must have caused current leak in the distributor cap.
Lasting rain fall causes many troubles on old and ancient historic automobile?

Utilizing lunch time, I came to the place that VW Beetle had been left because of disorder.
Trial replacements of ignition parts proved that the criminal of this affair was distributor cap, especially the central carbon terminal.
Replacement of distributor assembly could recover the motor running.
Deeper inspection must be necessary to know the error of new VW genuine replacement parts?
