Burning headlight fuses ?

Post by Lebouc »



Hi all,

Do any of you that changed their alternator for a 90 Amp one ever burnt headlight fuses afterwards ?
Since i changed my alternator for a 90 Amp one, i keep burning headlight fuses, only the headlight fuse but every ride though.
Someone ever had that problem and found a fix ?

Thank you !!

P.S : Great group by the way , awesome site !!!

No sir, it has never happened to me. However, I seriously doubt blowing fuses has anything at all to do with the an alternator.
Fuses blowing have everything to do with the load applied and not the supply available.

So how many dozen extra lights have been wired into the headlight circuit?

Hi, i don't have extra lights or any added accessories, the bike is stock nothing added, that's why i don't get it.
And before the 90 Amp alternator change, i've never blown a fuse , now it's one every ride . . . .
Coincidence ? i don't think so ?

Hi, the load is the same as it was before i changed the alternator, no lights or accessories added, the bike is stock from the factory,
that would be a hell of a coincidence don't you think ?

Just a thought, maybe, somehow, you pinched a wire doing the installation. That could account for a fuse blowing so often. I have done that before. If this has not happened before and all you have done is to change the alternator, I would think that you have pinched a wire during the installation or maybe pulled on a wire that got cut on a grounded part of the bike. Just check all the wiring around the area. Let us know what you find when you find it.

Those who say it cannot be done should try not to interrupt those who are doing it.
