1986 Honda CB700SC · Clutch & Oil-Warning Switches Buying guide
The 1986 CB700SC oil-pressure switch controls a warning circuit; the clutch-lever switch supplies a starter-safety signal. The oil switch is not a pressure gauge, and the clutch switch is not a hydraulic rebuild part. Locate the fault before selecting either one.
Honda’s oil-warning diagnosis separates the lamp and wiring from the pressure switch. A lamp that does not illuminate when expected can be a bulb or connection fault. If the lamp stays on with the engine running, stop the engine and have actual oil pressure checked before assuming the switch is to blame.
Honda specifies continuity when the clutch lever is applied and no continuity when released. A changed lever or master cylinder can affect actuation even when the switch itself is sound. Check the installed control and the starting circuit rather than bypassing the safety switch.
Not by itself. The warning can reflect low pressure, a switch fault or wiring trouble. Stop the engine if the lamp remains on while running, then verify oil level, the warning circuit and actual pressure using Honda’s procedure.
The lever must operate the clutch safety switch. Honda expects continuity with the lever pulled and no continuity with it released. Compare switch contact, pivot wear and wiring after a lever or master-cylinder change.
No. It switches the warning-light circuit; it does not supply a continuous pressure reading. A pressure test is a separate diagnostic step, not a value obtained by changing this switch.
