7-Series AL Ignition Controls
Within its bright red anodized aluminum case, you'll find tons of race-type features like a built-in Three Step Module Selector (with Soft Touch Rev Control to keep the rpm limiting action smooth and accurate). Four built-in timing retard modules that can be activated at different times to help enhance engine longevity under heavy nitrous usage or high rpm top end charges. An automatic 25A?A?A?A?A?A?A?A° start timing retard helps your engine fire-up quicker, especially if you're running a crank trigger or locked out distributor. And a 10 amp, rpm activated switch allows you to activate a solenoid, shift light, or other component at adjustable rpm. A thick layer of Humi-Seal blankets the MSD Ignition 7AL-3's internals and sturdy rubber vibration-proof mounts help combat vibration.
The MSD 7AL-3TM is based off the well proven MSD 7AL-2 Plus. It features a host of the most popular drag racing accessories. A built-in Three Step Rev Control provides three different rpm limits that can be used for the burnout, holeshot and top end overrev protection. There is also a Multi-Step Retard with four different modules that can be activated at different times. Four 0A?A?A?A?A?A?A?A° modules and a 2A?A?A?A?A?A?A?A°, 3A?A?A?A?A?A?A?A° and 4A?A?A?A?A?A?A?A° module are supplied. Many race engines with crank trigger systems or locked-out distributors will benefit from the 7AL-3's built-in Start Retard option. During cranking the Start Retard will retard the timing 25A?A?A?A?A?A?A?A° allowing the engine to turn over easier. When the engine starts, the timing will automatically go back to its mechanical setting. One last option is an RPM Activated Switch that allows you to activate a solenoid or shift light at an adjustable rpm. When the engine hits the desired rpm the RAS circuit provides a ground to the component to activate it. Vibration mounts, wires and detailed instructions are supplied.
