1986 Honda CB450SC Nighthawk · Switches & Sensors Buying guide

Identify the fitted switch by reference and control location

One switch is supplied for each of these compatible applications. Match the oil switch’s terminal and sealing arrangement, the rear pedal’s mechanically operated stop-light control or the clutch perch’s starter-safety switch. Choose each replacement for its original control or warning circuit.

Keep the rear switch purchase tied to the pedal control

The rear stop-light item is mechanically operated and used at the compatible rear-brake control. Its listing also recommends checks of bulb filaments, fuse, ground, connectors and wiring. Identify whether the control switch is actually needed before ordering a replacement to address a stop lamp that does not illuminate.

Compare the oil switch’s physical connection with its Honda reference

Several Honda numbers identify the genuine oil-switch replacement, including 35500-MJ4-024 and 35500-MB9-004. The listing requires comparison of the terminal and sealing arrangement against the original. Match those details together, and verify oil level, wiring and actual pressure if the warning symptom prompted the proposed switch purchase.

Switch Location & Reference FAQs

Which details should accompany an enquiry about the genuine oil-warning switch?

Give the Honda reference and compare the original electrical terminal and sealing arrangement. The listing includes 35500-MJ4-024, 35500-MB9-004, 35500-MJ4-014, 35500-MJ0-004 and 35500-MJ4-004. Confirm actual oil-pressure and wiring checks first if a persistent warning led to the enquiry.

What condition should I assess before ordering another rear stop-light switch?

Check the lamp filaments, fuse, ground, connectors, wiring and switch continuity. The rear switch is mechanically operated at the brake control; a replacement cannot correct a separate failed bulb or open circuit. Use those checks to establish the needed component.

What should I compare before purchasing a replacement for the clutch perch?

Match Honda 35330-413-003 and inspect the lever contact point, connectors and wiring. The detailed application is the clutch starter-safety switch, despite brake-light wording in its title. Follow the wiring diagram for checks instead of bypassing the interlock.
