Setup and Installation
Proper installation is critical for the performance and longevity of your MSD Blaster HVC-2 Ignition Coil. Always disconnect the vehicle's battery before beginning any electrical work.
Tools Required:
- Wrench set
- Screwdriver set
- Wire strippers/crimpers
- Multimeter (for testing, optional)
Mounting the Coil:
- Select a mounting location that is cool, dry, and away from direct engine heat or excessive vibration. Ensure sufficient clearance for wiring and spark plug wire.
- Use the provided vibration mounts to secure the coil. These mounts help absorb engine vibrations, protecting the coil's internal components.
- The coil can be mounted using either the screw-in or bolt-on method, depending on your application and chosen location.

Wiring Connections:
Refer to your specific ignition system's wiring diagram for precise connections. The Blaster HVC-2 coil is designed to work with MSD 6-series ignition controls.
- Connect the positive (+) terminal of the coil to the positive output of your MSD ignition control.
- Connect the negative (-) terminal of the coil to the negative output of your MSD ignition control.
- Ensure all connections are clean, secure, and properly insulated to prevent shorts.
- Install the high-tension spark plug wire from the coil's output tower to the distributor cap or appropriate ignition component.

Operating Principles
The MSD Blaster HVC-2 Ignition Coil operates by transforming low voltage from the vehicle's electrical system into the high voltage required to create a spark across the spark plug gap. When paired with a compatible MSD ignition control, it delivers multiple sparks at lower RPMs and a powerful single spark at higher RPMs, ensuring complete combustion and improved engine performance.
This coil is designed for continuous high-output operation in demanding environments, making it suitable for racing and high-performance street applications.
Maintenance
The MSD 8253 Blaster HVC-2 Ignition Coil is designed for minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.
- Visual Inspection: Regularly inspect the coil and its wiring for any signs of damage, corrosion, or loose connections. Ensure the high-tension spark plug wire is securely seated.
- Cleanliness: Keep the coil housing clean and free of dirt, oil, and moisture. Use a clean, dry cloth for wiping. Do not use harsh chemicals or solvents.
- Mounting Security: Periodically check that the coil is securely mounted and that the vibration mounts are intact and not deteriorated.
No internal user-serviceable parts are present. Do not attempt to disassemble the coil.
