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 MSDWhite.

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 several times.

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.
