1982 Honda CB650SC Nighthawk Ignition Coils & Key Switches

Ignition service on the 1982 CB650SC begins with identifying the system and testing the affected circuit. The stock-type coil and keyed switch have different ordering details. Aftermarket ignition changes need their own resistance and connection checks before another coil or spark unit can be selected.

1982 Honda CB650SC Nighthawk · Ignition Coils & Key Switches Buying guide

Compare the coil inventory and complete switch

The selected coil has a separate high-tension wire requirement, while the ignition switch supplies its own keys and fork lock. Identify each fitted assembly before choosing parts for a changed ignition or wiring harness.

Parts to consider

Account for the coil’s separate leads

Coil 17-6803 is sold individually and requires separately supplied 7 mm high-tension wires. Its replacement references are 30500-422-003 and 30500-422-013. The complete record does not establish spark-plug cap inclusion, so confirm that detail if caps are also needed.

Identify the complete replacement switch

Switch 12-0051 supplies the ignition and fork-lock assembly with keys. Its replacement references include 35100-422-017 and 35100-438-007. Compare the fitted connections and mounting, especially after wiring or control changes.

Ignition Coils & Key Switches questions

Will the ignition keys also work in my existing seat or helmet lock?

The switch listing confirms keys for its ignition and fork-lock assembly only. It does not promise a match to a separate seat or helmet lock. Confirm a key-matching solution before ordering if retaining one-key operation matters.

Does the coil reference establish a match to a converted ignition?

The coil listing does not specify primary resistance. Obtain the coil specification and compare it with the installed ignition manufacturer’s requirements; the replacement reference alone does not establish compatibility with a changed system.

Does one coil order replace both coils on the motorcycle?

No. The featured replacement coil is sold individually, and the listed original system uses two coils. Order two if diagnosis calls for replacing both. Check the fitted ignition and lead requirements before choosing the replacement quantity.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
