Xpken,

What your described sounds sort of strange. IE Normally when a fuse blows something stops working.

More information would be helpful IE Does anything not work when this fuse blows? What items are protected by this fuse? Have you tried disconnecting the other things protected by this fuse to see which item might be shorting out and blowing the fuse. Is this the amp meter for your alternator or your battery charger?

Not sure about this but, at this time it sounds like you have a short, like an exposed wire that only shorts sometimes, which blows the fuse and puts full amps from the battery to your amp meter, which pegs it.
