FAQ
Will the 71281D fit my dual-point distributor?
It is made for 1960 to 1973 Ford and Mercury V8 dual-point vacuum-advance distributors. Match the distributor casting number against the Pertronix list before ordering.
What coil should I run with the 71281D?
Use a low-resistance coil of about 0.32 ohm, such as a Pertronix Flame-Thrower III. The Ignitor III is designed around that value for full output.
Does it keep the vacuum advance?
Yes. The kit converts the trigger to electronic while the distributor keeps its original mechanical and vacuum advance.
Is a ballast resistor needed?
No. The Ignitor III uses a full 12 volts on a negative ground system and does not require the factory ballast resistor.
