Today I noticed that the headlight on my CBF250 was out. Not a big deal - with winter over I seldom ride in the dark. The dim & main was gone so I doubted it was a blown bulb. The first thing I checked was the fuse and the problem was not hard to spot.

| Not only had the 10A fuse blown, the plastic body had melted. |

| The CBF's fuse box |

| I checked the current through the fuse in case there was a short circuit. The headlight is 55 watts on dip and 60 watts on main so I'd expect 5 amps - and that's what I got. |
Why the fuse blew will have to remain one of life's mysteries.
...or maybe not. My brother said that the problem could be a bad contact causing arcing. I cleaned the contacts in the fuse box and now all seems well.

The problem returned some months later and I found the real fault. https://fjstuart.blogspot.com/2019/12/cbf-headlight-problem.html

Chinese Fuse?

DeleteI can't remember ever replacing the fuse so maybe it's original. But it could be from my cheap fuse kit.
