[dsn_klr650] blown headlight fuse
Posted: Wed Aug 02, 2000 10:16 am
a while back some clever electronics-smart chap posted that the wiring
system seemed to be fully adequate for a 15 amp fuse (with normal extra
tolerance), and that as a result you should be able to use a 15a fuse for
the headlight without any problem. he further theorized that the fact that
both lights are on in the middle could be stressing the 10a fuse just in
normal switching back and forth, causing the high fuse failure rates that
some folks have experienced.
my fuse died on a DARK twisty mountain road in the middle of the night.
fortunately i was on a short straightaway, and i know the road pretty well.
i put in a 15a fuse to replace it (this was about 4 months/8000 miles ago)
and it's been working great ever since. i know of no one who has fried
anything by using the bigger fuse.
