Reply to "Parts needed to convert duraspark?"

I did not mean to imply the Duraspark dizzys wear out faster than the breaker point dizzys. All Ford dizzys have the same problem. Its just that the subject is Duraspark. If you don't believe a Ford dizzy is worn out in 50,000 miles, put a 50,000 mile dizzy on a distributor machine and observe the operation of the advance mechanism compared to the advance mechanism of a new or rebuilt dizzy. The bushings will have play in them as well, which really played havoc with breaker points.

I believe the relay in the drawing is necessary, that's why I carefully and deliberately put it there. Its purpose is to route the current flowing to the module in another manner rather than flowing through the ignition switch, which when taken apart every Pantera owner will find is a dirty charred high resistance mess; and results in a voltage drop if the current to the module is left to flow through the ignition switch. The module will work best if it receives full battery voltage as intended.

The large Duraspark distributor cap was necessary to prevent crossfire, which is not the same as scatter. The coils on Duraspark equipped cars are still mounted on the intake manifold but they are mounted at a 45 degree angle, with the top higher than the bottom. You're wrong about the other colored modules (brown, yellow, white) indicating the number of cylinders. If you are getting away with no balast resistor supplying the coil with a Duraspark II module its because there is at least 1 ohm resistance in your circuit supplying the coil.
