The PerTronix Ignitor II for Ford V8 distributors with Load-O-Matic or Dual Advance vacuum units upgrades your classic Ford with microprocessor-controlled ignition timing. Designed for 289, 302, 351W, 390, 428, and 460 Ford V8s from the 1960s and 1970s, this module replaces the troublesome Ford points system with adaptive dwell control for consistent spark energy.

This Ignitor II variant is designed specifically for Ford distributors with the dual-advance vacuum mechanism and includes the proper magnet sleeve profile for Ford's distributor shaft diameter and length. The microcontroller adjusts coil dwell from 3 to 15 milliseconds depending on engine speed, maximizing coil saturation at idle while preventing coil overheating at high RPM. Operates on 6-16 volts DC with included wiring harness. The Hall-effect sensor is epoxy-potted and the module fits entirely under the Ford distributor cap without any clearance issues.

Ford points distributors are notorious for point float above 5,000 RPM and rapid wear from the heavy Ford advance springs. The Ignitor II eliminates these issues entirely, allowing clean spark delivery to 7,000 RPM. You'll also notice improved cold-start behavior and smoother idle with the optimized low-RPM dwell. Installation removes the existing points plate and replaces it with the Ignitor module — about 25 minutes with basic hand tools.

Stop fighting with Ford points adjustment. Install the PerTronix Ignitor II and enjoy the reliable electronic ignition your Ford always deserved.

Frequently Asked Questions

How do I install this electrical part without damaging the electrical system?

Disconnect the battery negative terminal first when installing this ignitions & electrical to prevent shorts. Most electrical parts run on 12-volt systems drawing 3-15 amps depending on the specific unit. Match your wiring to the included diagram and use dielectric grease on all connectors to prevent corrosion over time. Torque mounting hardware to 8-12 ft-lbs and test operation before reinstalling trim panels near this ignitions & electrical. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

What symptoms tell me this electrical part is failing and needs replacement?

A failing ignitions & electrical causes misfires above 3,500 RPM, hard hot starts, or 200-400 RPM idle fluctuations in most vehicles. Check primary resistance with a multimeter readings outside 0.5-to-3.0 ohms indicate a bad component. Voltage below 12.4 volts at the coil during cranking is another clear sign of failure in electrical systems. Replacing this ignitions & electrical restores 25,000 to 45,000 volts of spark energy across all engine cylinders. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

Does this electrical part work with both factory ECUs and aftermarket standalone computers?

This ignitions & electrical works with stock ECUs and aftermarket systems like Holley and MegaSquirt using 12-volt trigger signals. Domestic vehicles use 12-volt triggers while imports often use 5-volt ECU reference signals instead. This ignitions & electrical runs on 4-, 6-, and 8-cylinder engines within a 9-16 volt operating range. Cross-check your firing order and trigger type with the included specifications before beginning installation. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

Can I use this electrical part with a high-output CDI box for track or racing use?

Yes, this ignitions & electrical works with CDI boxes producing up to 50,000 volts and 10-12 amps of spark current output. Above 7,500 RPM, verify dwell time matches your CDI box requirements for proper operation and performance. Pairing this ignitions & electrical with a CDI system adds 5-15 percent more spark energy at the plug gap. Keep primary resistance above 0.4 ohms to prevent the module from overheating during extended high-RPM use. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

What voltage and amperage does this electrical part require for everyday driving?

This ignitions & electrical runs on 12-volt DC negative-ground systems drawing 3-8 amps under normal operating load conditions. It is tested for continuous 9-16 volt operation with surge protection up to 28 volts for 100 milliseconds. Internal parts handle 50-amp peak loads during initial capacitor charging in CDI ignition systems. Confirm your alternator outputs at least 13.5 volts at idle for consistent electrical component performance. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

Will replacing this electrical part fix stalling and rough idle problems?

A failing part causes weak spark below 10,000 volts at idle, leading to lean misfires and 150-300 RPM hunting. Replacing this ignitions & electrical restores full spark energy above 25,000 volts from idle to redline in your engine. Also check spark plug gaps at 0.035-0.045 inch and fuel pressure at 48-62 PSI for a thorough fix. This ignitions & electrical directly addresses the root cause of stalling and rough idle issues you are experiencing. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.
