250V HEAD fuse?

[Guest]

Bike will not start after I just replaced all my fuses per what the fuse box cover says, from top to bottom:

10A
10A
10A
15A
10A

I noticed the one of the old fuses, the first fuse from the top, which the cover says is "HEAD", had a fuse which said "250V"

I put that fuse back in and the bike starts. What gives?

Thanks for any light you can shed on this.

The fuse is rated for use up to 250 volts @ 10 amps. If you take fuses in and out and things randomly work, I suspect you have corrosion. You need bright and shiney connections everywhere. Dialectric grease keps it from corroding after it's shined.

I agree there is probably corrosion. When all is working I can jiggle them all over the place and nothing, i.e., it's impossible actually hard to make it fail. Then when it does fail I just tap on the fuse box cover and the head lights come back on and the warnings on the dash go out. I found my bottle of DeoxIT and I will give them all a good cleaning/soaking. Thanks

When you have corrosion on one part, there is likely more elsewhere, so look at other connectors as well.

While you are doing the clean-up, do yourself a favour and add a second cable from the negative terminal on the battery, as a supplementary ground, and fasten it to the bike at a second, clean, location.

A poor ground can lead to failure of more expensive parts, like R./R and stator, so this is cheap insurance.
