CHECKING FOR SPARK
If triggering the ignition with the White or White/Blue
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 or White/Blue 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 or White/Blue wire to ground quickly
several times (Figure 16). Each time you pull the wire
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:
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 quickly several
times (Figure 17). Each time you break this short, 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 a known good 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 are 12 volts on the small Red wire from the MSD when
the key is in the On position. If 12 volts are 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.
