Remove the coil boot and look to see if there is carbon tracking on the tower of the coil. If any sign of carbon is present then you will need to replace the coil. Also at the same time replace the coil wire as well, it may also be damaged.

MSD does stand behind its products. Your MSD Coil has a 1 year warranty and can be returned to MSD for inspection. Below is the information on our warranty policy.

Autotronic Controls Corporation warrants MSD Ignition products to be free from defects in material and workmanship under normal use and if properly installed for a period of one year from date of purchase. If found to be defective as mentioned above, it will be replaced or repaired if returned prepaid along with proof of date of purchase. This shall constitute the sole remedy of the purchaser and the sole liability of Autotronic Controls Corporation to the extent permitted by law, the foregoing is exclusive and in lieu of all other warranties or representations whether expressed or implied, including any implied warranty of merchantability or fitness. In no event shall Autotronic Controls Corporation be liable for special or consequential damages.

In case of malfunction, your MSD component will be repaired free of charges according to the terms of the warranty. When returning MSD components for warranty service, Proof of Purchase must be supplied for warranty verification. After the warranty period has expired, repair service is charged based on a minimum and maximum charge rate. (Contact Customer Service for current rate).
When returning an MSD product for repair, leave all wires at the installed length. Cutting wires close to the unit will void the warranty. Also, include a detailed account of any problems experienced and what components and accessories are installed on the vehicle.

If you are running an MSD Capacitive Discharge Ignition like an MSD 6 or 7 Series, you do not need to run the ballast resistor on the 12 volt line. If you are running just the coil with points or an inductive ignition, then you will need to run the resistor.
