1986 Honda CB450SC Nighthawk Signal Circuit and Mount Orders

Prepare turn-signal repairs on your 1986 CB450SC Nighthawk by separating the flasher circuit from the rear stay mountings. The flasher relay needs reference matching, while paired rubbers cushion the rear stays. Establish which parts need renewal and how their stated supply quantities apply.

1986 Honda CB450SC Nighthawk · Turn Signal Lamps, Stems, Lenses & Reflectors Buying guide

Identify the flasher replacement and count the stay rubbers separately

The relay’s listed applications include 1986 CB450SC models and its Honda cross-references guide identification. Rear-stay rubbers have a different purchase calculation: two are supplied per pack and two are used on each compatible rear signal.

Do the circuit checks before settling on a flasher purchase

Burned-out lamps, incorrect bulb wattage, poor grounds, connector corrosion and damaged wiring can produce symptoms resembling a failed relay. Assess those listed possibilities and compare the fitted Honda reference before choosing the replacement. The relay description provides no separate LED-load rating or conversion guarantee to apply to changed lighting.

Build the mounting order around each rear stay being serviced

Each rear signal requires two rubber cushions, with one matching pair supplied per pack. While counting the mounts, inspect the brackets, collars, washers and fasteners for missing or bent pieces. Include damaged adjoining hardware in the repair assessment instead of assuming fresh rubber resolves every mounting fault.

Signal Circuit & Stay Orders FAQs

How do I use the relay reference when more than one Honda number is listed?

Compare the original number with the stated cross-references, including 38301-MG9-681 and 38301-KK9-952. The relay application includes 1986 CB450SC models. Check the signal circuit as well, since poor bulb, ground or connector condition can imitate the need for a new relay.

What quantity applies if only one rear signal’s cushions need replacement?

One pack supplies the two rubbers required beneath one compatible rear signal stay. Renewing the cushions at both rear signals requires two packs. Count the actual signals being serviced rather than treating one pack as a pair of complete rear mounts.

What compatibility information is missing if I have changed the signal bulbs to LEDs?

The listing gives Honda relay cross-references but no LED-load rating or conversion compatibility statement. Confirm suitability for the fitted lamps before purchase. Its circuit checks include incorrect bulb wattage, poor grounds and damaged connections; those details still need assessment.
