1978 Honda CB400TII Hawk II · Fuse Box Buying guide

Check what the complete assembly replaces

The fuse box is supplied with fuses, making it a practical replacement for a damaged holder assembly. Inspect its cover, mounting and connector against the old part before starting work. Keep any issue in the mating harness in the repair plan rather than expecting a new box to correct damaged wiring.

Treat repeated fuse failure as a fault to investigate

A fuse that blows again calls for circuit diagnosis, not a higher rating. Use the Hawk II wiring diagram to identify the protected circuit and inspect the connected wiring and loads. Correcting the cause before fitting the replacement assembly helps avoid repeating the same damage.

Common buying questions

Are fuses supplied with the replacement box?

Yes. Fuses are included with this complete replacement assembly. Check each circuit against the motorcycle wiring information when fitting the unit, especially if an earlier owner changed the wiring or fuse values.

Does the box use the original mounting pattern?

It is listed for the 1978 CB400TII with reference 38200-413-003. Compare its mounting ears and connector to your existing assembly before ordering, particularly on a motorcycle with a changed harness.

Will a new fuse box cure a fuse that keeps blowing?

Only if the holder itself is the diagnosed problem. Repeated fuse failure can involve wiring or a connected load, so identify the cause and retain the correct fuse rating before replacing the assembly.
