Airtex 6R1002 Ignition Coil Ballast Resistor

The Airtex 6R1002 is an ignition coil ballast resistor designed to protect your vehicle's ignition system from electrical overload. This critical component regulates the voltage supplied to the ignition coil during normal engine operation, preventing overheating and extending the life of your ignition components.

Key Features:

• Limits electrical current flow to the ignition coil to prevent damage
• Reduces voltage after engine start to protect points and electronic ignition modules
• Helps prevent premature ignition component failure
• Essential for vehicles with breaker point distributors and some electronic ignition systems
• Typically mounted on the firewall or near the ignition coil

Function:

During engine cranking, the starter sends a higher amperage to the spark plugs to fire up the engine. Once running, this ballast resistor steps in to reduce the amperage, preventing the ignition coil from overheating. Without a functioning ballast resistor, the ignition coil and points can overheat and fail prematurely, leaving you stranded. This component is commonly used in older ignition systems and aftermarket electronic ignition conversion kits.

Symptoms of a Failing Ballast Resistor:

• Engine dies immediately after starting
• No-start condition
• Intermittent ignition problems

Replacing a worn ballast resistor is a simple and affordable way to ensure reliable ignition performance and protect more expensive ignition components from damage.
