Mallory Unilite Wiring Diagram: A Comprehensive Guide

For those who own classic cars, the Mallory Unilite ignition system is a popular choice. It is known for its reliability, ease of use, and maintenance. However, wiring the Mallory Unilite system can be a challenge for those who are not familiar with how it works. In this article, we will discuss the Mallory Unilite wiring diagram and provide you with all the information you need to successfully wire your system.

What is the Mallory Unilite Ignition System?

The Mallory Unilite ignition system is an electronic ignition system that replaces the original distributor and points-style ignition. The Unilite system uses an infrared signal to trigger the ignition coil, providing a more reliable and consistent spark. This system is commonly used in classic cars as a performance upgrade.

How Does the Mallory Unilite Ignition System Work?

The Mallory Unilite ignition system works by using a rotating shutter wheel and an infrared sensor to trigger the ignition coil. As the shutter wheel rotates, it blocks and unblocks the infrared signal. When the signal is blocked, the sensor triggers the ignition coil to produce a spark. This system requires a 12-volt power source and a ground connection to operate.

What are the Benefits of the Mallory Unilite Ignition System?

The Mallory Unilite ignition system offers several benefits over the original points-style ignition. These benefits include:

Benefit Description
Reliability The Unilite system is more reliable than the original points-style ignition, which can wear and fail over time.
Consistency The Unilite system provides a more consistent spark, which can improve engine performance and fuel economy.
Easy Maintenance The Unilite system requires very little maintenance, as it does not have any moving parts that need to be adjusted or replaced.

FAQs

What is the difference between the Unilite and Dual-Point Ignition Systems?

The Unilite ignition system uses an electronic sensor to trigger the ignition coil, while the dual-point system uses two sets of points to trigger the coil. The Unilite system is more reliable and consistent than the dual-point system.

Can I use the Mallory Unilite Ignition System with my original distributor?

No, the Mallory Unilite ignition system requires a specific distributor that is designed to work with the Unilite module. You cannot use the Unilite module with your original distributor.

Does the Mallory Unilite Ignition System require any special maintenance?

No, the Mallory Unilite ignition system requires very little maintenance. However, it is important to check the wiring and connections periodically to ensure they are secure and in good condition.

Can the Mallory Unilite Ignition System be used with a high-performance engine?

Yes, the Mallory Unilite ignition system is designed to work with high-performance engines. It provides a consistent spark and works well with aftermarket performance components.

Can I install the Mallory Unilite Ignition System myself?

Yes, the Mallory Unilite ignition system can be installed by a knowledgeable DIYer. However, if you are not comfortable with wiring or working on your vehicle’s electrical system, it is best to have a professional install the system for you.
