How It Works: The ballast resistor is installed in series with the ignition coil’s primary circuit. During normal engine operation, it limits the current flow to protect ignition components. When starting the engine, the ballast resistor is bypassed through a jumper wire circuit, allowing full battery voltage to reach the ignition coil for maximum spark energy during the critical starting phase.
Quality Assurance: Fuelmiser leads the aftermarket with quality parts sourced from world-leading OEM and OES manufacturers. Each ballast resistor undergoes rigorous testing to ensure it meets or exceeds original equipment performance standards, providing reliable operation in demanding automotive environments.
