Single Wire Ignition Upgrade
Keeping the spark in your old GM V-8
Created by Dave AndersonIf your classic GM V8 is throwing a spark across a set of points, then you've either become proficient at adjusting and replacing those points or have paid out a fortune over the years to a mechanic to maintain the spark in your classic. Well, toss out your dwell meter because M&H Electric Fabricators has an electronic ignition upgrade conversion that is so easy to install you'll be shocked.
Stock Appearance
The BREAKERLESS SE Single Wire Ignition from M&H Electric Fabricators allows you to convert any 1957 to 1974 GM V8 (or AMC and Jeep) breaker point type distributor to a reliable solid-state electronic ignition. This ignition utilizes a fully integrated trigger and power module that fits completely inside the distributor. And, unlike other competitive offerings, no additional wires protrude from the distributoronly the original single wire from the distributor. The result is a state-of-the-art ignition upgrade with an absolutely stock appearance.
No more burned points, higher ignition voltage, more accurate timing, longer plug life, faster starts, increased fuel economya virtually maintenance free ignition system that those concours judges will never be able to detect. Yes, in addition to these performance and maintenance gains, your car retains its stock underhood appearance as the BREAKERLESS SE is the ONLY single wire module on the market.
Easy Conversion
And better yet, any shade tree mechanic can easily make the conversion without removing the distributor from the vehicle. Since our distributor was showing its age, we elected to remove and rebuild the entire distributor. You too may want to go this route as well, but one of the many benefits of the BREAKERLESS SE's design is that it compensates for worn bearings and distributor end play.
This single wire ignition conversion comes with everything you need to complete your installation. The kit includes the module, a two piece vane assembly, all necessary mounting hardware, a screwdriver, and complete step-by-step instructions. With our distributor out of the car, the upgrade took a mere 15 minutes. And once reinstalled in our car, the engine fired on the first click of the starter. This ignition upgrade will not only add spark to your GM V8, you'll gain years of maintenance free cruising.
Benefits
> Single wire operation to preserve stock appearance and simplify wiring.
> Active dwell control to maintain high rpm spark energy while reducing coil heating at idle.
> Auto shut-off to prevent coil damage or dead battery if the ignition is accidentally left on.
> Over-voltage/over-current protected against damage from high amp batter chargers, reverse battery polarity or improper wiring.
> Hall Effect rotary-vane sensor design compensates for worn bearings and distributor end play. Magnetic sensor is unaffected by oil, dirt or other contaminants, unlike optical systems.
> Over-voltage protected against damage from high amp battery chargers, reversed battery or improper wiring.

Step 3
Installation is simple. The two vane sections are joined together, first at one end with one of the button-head screws. The vane sections are split and inserted below the rotor. Next, the button-head screw is thread up from the underside of the rotor. The screws are then tightened firmly with the supplied 1/8-inch hex wrench.

The module is then fit into place and attached with the supplied screws. Finally, the existing "single wire" is attached with the brass screw to the module and the installation is complete. All that is left is replacing the rotor and distributor cap and you're ready to run.
