CHECKING FOR SPARK
If triggering the ignition with the White wire:
1. Make sure the ignition switch is in the "Off" position.
2. Remove the coil wire from the distributor cap and set
the terminal approximately 1/2" from ground.
3. Disconnect the MSD White wire from the distributor's
points or ignition amplifier.
4. Turn the ignition to the On position. Do not crank the
engine.
5. Tap the White wire to ground several times (it takes
several times to trigger). When the wire is removed
from ground, a spark should jump from the coil wire
to ground. If spark is present, the ignition is working
properly. If there is no spark skip to step 6 below:
If triggering with the Magnetic Pickup:
1. Make sure the ignition switch is in the "Off" position.
2. Remove the coil wire from the distributor cap and set
the terminal approximately 1/2" from ground.
3. Disconnect the MSD magnetic pickup wires from the
distributor.
4. Turn the ignition to the On position. Do not crank the
engine.
5. With a small jumper wire, short the MSD's Green and
Violet magnetic pickup wires together several times
(it takes several times to trigger). A spark should jump
from the coil wire to ground. If spark is present, the
ignition is working properly. If there is no spark skip to step 6 below:
6. If there is no spark:
A. Inspect all of the wiring.
B. Substitute another coil and repeat the test. If there is now spark, the coil is at fault.
C. If there is still no spark, check to make sure there is 12 volts on the small Red wire from the MSD
when the key is in the On position. If 12 volts is not present, find another switched 12 volt source
and repeat the test.
D. If, after following the test procedures and inspecting all of the wiring, there is still no spark, the MSD
Ignition is in need of repair. See the Warranty and Service section for information.
