Lucas Ballast Resistor - SCB400

A ballast resistor is an electrical component used in ignition systems to regulate the voltage supplied to the ignition coil.

The SCB400 helps to improve engine performance by regulating voltage and protecting the ignition coil.

Consult your vehicle's service manual or a qualified mechanic. The resistor typically mounts in the engine compartment, and the wiring connections must be secure.

Use a multimeter to measure the resistance across the resistor. It should read approximately 1.6 Ohms. Also, check for visual signs of damage, such as cracks or burns.

The SCB400 is only one component of the ignition system. Other components, such as the coil, distributor, and spark plugs, may also be faulty. Consult a mechanic for further diagnosis.

The Lucas SCB400 is available through various automotive parts suppliers and online retailers.

The weight of the SCB400 is 0.2 kg.

Check the connections to the ballast resistor. Test the resistance with a multimeter to ensure it matches the specified value of 1.6 Ohms. Replace if faulty.

Inspect the wiring and connections for any damage or corrosion. Ensure the resistor is correctly installed and compatible with the ignition system. Consider replacing the resistor if the misfire persists after checking other components.

Check for correct wiring and ensure the resistor is properly mounted. Overheating can be a sign of a short circuit or an incorrect resistor being used. Consult a mechanic if the problem continues.
