FEATURES

RPM LIMITERS

The 7AL-2 Plus Ignition is equipped with a 2-step rev control. The Ignition will accept two rpm

modules so two different rev limits can be set. One rev limit can be used for overrev protection while

the second limit can be activated on the starting line for a lower rpm limit to assist in staging and

for consistent holeshots. When 12 volts are applied to the 2-step terminal (2’S’), Module 1 is active.

Module 2 is active when there is no 12 volts.

CYLINDER SELECT

This ignition can be used on 2, 4, 6 (even-fire) or 8-cylinder engines. The ignition is set for 8-cylinder

operation. To program the unit for other engines, remove the one screw that holds the cover to reveal

three wire loops (Figure 1). Cutting a wire loop determines the cylinder selection.

SPARK LED

When the coil fires, current is sensed and this

LED will flash. This confirms that the ignition has

received a trigger signal and that the coil and

ignition are working properly. (If the coil is not

connected, the LED will not flash.) When the

engine is running, it will appear solid.
