I have a 2007 Hayabusa bought with less than 5,000 miles and currently has 24,836. About a month ago the starter relay fuse popped - traced the problem to an internal short in the voltage regulator. Because OEM new ones are pretty expensive, I bought a used OEM from eBay. Bike ran and charged well since, but yesterday while riding the battery went dead. Stopped and the bike just wouldn't start. I once again traced the problem to the voltage regulator but it wasn't the same problem as the first time - no blown starter relay fuse, This time it is just not charging the battery and tested bad using a multimeter. I know I bought used but wonder if the first and second failure (although the cause of the failure is different) might be a result of another component in the electrical system causing the voltage regulators to fail. Or was the second failure just a fluke and possibly attributed to buying used. Also, even though the price of the one offered at Powerhouse Motorcycles is very similar to OEM, is it still the consensus that the one from Powerhouse is the better choice?
