MSD SYSTEMS Installing to Points/Amplifier Style Ignition.
Figure 9 Checking for Spark with Magnetic
Pickup.
MAGNETIC PICKUP TRIGGER
NOTE: On dual point setups, it is recommended
to remove the trailing set of points.
NOTE: Ballast Resistor is not necessary.
NOTE: Remove the coil
terminal wires. The negative
wire connects to MSD White.
The positive wire connects
to MSD Red. The MSD
Orange connects to the
coil positive terminal, Black
connects to the coil negative
terminal.
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. 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 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.
The following wiring diagrams illustrate numerous installations on different vehicles and applications.
