Mine was already replaced once, along with two batteries I went through because of it. Luckily the rectifier was under warranty when it went out, but I was left bikeless in Daytona Beach.. They wouldn't replace the batteries though. The only thing I wonder about now is, did they replace it with the same one that has been prone to fail? It's not under warranty now, and I really don't want to be stranded again at Bike Week in Daytona!!!
