How can ferrite beads be used to suppress ignition noise? Install them:

🔍 Key Concepts

• Ferrite beads as radio-frequency (RF) chokes • Where ignition noise is generated and how it travels (primary vs. secondary ignition circuits) • Difference between power leads, antenna leads, and ignition leads

💭 Think About

• On what wires does ignition noise from spark generation primarily appear and travel toward radios and electronics? • What is the electrical effect of a ferrite bead on high-frequency interference compared to low-frequency power or DC current? • Which option places ferrite beads where they will most directly choke RF noise at its source rather than far away in the system?

✅ Before You Answer

• Identify which circuits are actually part of the ignition system (primary and secondary) versus unrelated circuits like starter or antenna only. • Consider that ferrite beads act as high-frequency impedance: they block RF noise but allow normal DC/low-frequency current to pass. • Verify which answer choice locates the beads on the leads that carry the ignition pulses that create the interference.
