FAQ
Which Mallory distributors does the 7ML-181 fit?
It fits Mallory 25, 26, YD, and YL series 8-cylinder distributors. The YL670AV is not covered. Confirm the distributor model against the Pertronix list before ordering.
What coil should I use?
Use a low-resistance coil of about 0.32 ohm, such as a Pertronix Flame-Thrower III, to get full Ignitor III spark output.
Does the 7ML-181 need a ballast resistor?
No. The Ignitor III runs on a full 12 volts on a negative ground system and does not use the factory ballast resistor.
What are the benefits over points?
Electronic triggering removes points maintenance, and adaptive dwell plus multiple spark deliver a stronger, more consistent spark across the rpm range.
