FAQs
What is the primary benefit of the MSD Digital 6A?
The primary benefit is significantly improved engine performance through more complete fuel combustion, achieved via a higher output spark and multiple sparks per firing stroke.
How easy is the installation process?
Installation is made easier with a single sealed connector for wiring. However, it still requires proper connection to the vehicle's electrical system and trigger source.
What RPM range does the multiple spark feature cover?
The multiple sparks feature is active up to 3000 RPM, aiding in easier starting and improving throttle response during initial acceleration.
Can this unit be used with a stock ignition system?
The Digital 6A is an upgrade that works with various trigger sources like breaker points or electronic amplifier outputs, but it replaces or enhances the stock ignition control module, not necessarily the entire system.
What electrical system voltage is required?
The unit works with virtually any 12-18 volt electrical system.
What are the dimensions of the unit?
The dimensions are 302mm x 102mm x 46mm.
Does it improve fuel economy?
Yes, by improving fuel combustion, it can lead to better fuel economy.
Troubleshooting
Engine will not start or runs poorly
Verify all wiring connections are secure and correctly made according to the included instructions. Check the voltage supply to the unit (12-18V). Ensure the trigger source (points, pickup) is functioning correctly and set to manufacturer specifications.
No spark or weak spark
Double-check the primary and secondary wiring connections. Inspect the ignition coil for proper operation. Ensure the unit is receiving adequate power. Test the trigger signal input.
Intermittent performance issues
Check for loose connections, especially in high-vibration areas. Ensure the unit is not overheating. Verify the trigger signal is stable and free from noise.
Reduced fuel economy or power loss
Confirm that the unit is correctly wired and functioning. Ensure spark plugs are gapped correctly for the higher energy output. Check for other engine issues (e.g., fuel delivery, vacuum leaks) that might be affecting performance.
Pros and Cons

Setup, Compatibility & Care
Setup: Installation involves connecting the unit to the vehicle's 12-18 volt electrical system and to the ignition trigger source (breaker points, magnetic pickup, or electronic amplifier output). All necessary parts and wiring instructions are included in the package. It is recommended to consult the included wiring diagram carefully.
Compatibility: The MSD Digital 6A is designed to work with virtually any 12-18 volt electrical system. It is compatible with engines utilizing breaker points, magnetic pickups, or the output of an electronic amplifier as their trigger source.
Care: The unit requires minimal maintenance. Keep the wiring connections clean and secure. Ensure the unit is mounted in a location protected from excessive moisture and vibration. Regular inspection of spark plugs for fouling can indicate the effectiveness of the combustion process.
