INSTALLATION INSTRUCTIONS

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 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.

The following wiring diagrams illustrate numerous installations on different vehicles and applications. If
