Note:
Signs that your regulator needs replacing:
Depending on the location of the regulator rectifier, the part can easily overheat. Other causes for a dead regulator rectifier center on the battery. Ground connections are important for good voltage, and if there is a faulty voltage, the regulator rectifier can run hot. Bad grounding, corroded battery connection and poor or loose battery connections will cause faulty voltage too.

There are generally two ways for the regulator rectifier to fail:
The first deals with diode burnout, resulting in battery drain. It is easy to assume that the issue is a bad battery because of symptoms such as dimming headlights and poor starts. Checking the voltage with a voltmeter versus relying on symptoms alone will prove highly beneficial. If the voltage drops below 13 volts, the motorcycle will begin to drain the battery and eventually the engine will stop. Check for bad connections and corrosion; these can also cause voltage issues.
The other failure type is shunt regulator burnout, where the regulator rectifier fails to control the voltage, resulting in battery overcharge. Again, a voltmeter will be useful for diagnosis. Though generally, readings above 17 volts mean the regulator rectifier is not converting the excess power correctly and all of that excess voltage may cause the headlights to become extremely bright and then blow.

Annoying sound but DOGGY TOY JOY!!
Pattern Name: Skunk
My 14 month old is squeaker OBSESSED, but she easily does surgery and defluffs. However this toy has been perfect. The sound when you shake is over the top and creates so much excitement. She loves to chase and chew this and play tug with this, and no tears from tug or points where she's tried to excise squeaker so far!

Great toy loved by 3 big dogs
Pattern Name: Skunk
We have a black lab and 2 grandpups (a Great Dane and a Cane Corso) that visit regularly. All 3 love this toy. All 3 destroy toys pretty quickly, sometimes within minutes. I have no idea what it is about this one, but they have not even remotely destroyed it except for major slobber damage from being so loved. I bought the first one months ago from TJ Maxx and then bought another on here thinking it could be a replacement when the first one got destroyed. The first one has yet to be destroyed. It sounds like there is a water bottle inside of it but it is some kind of coil thing. That being said, this toy can be very annoying to listen to, but we tolerate it for 3 very happy dogs.

Not for us, unfortunately.
Pattern Name: Chipmunk
Cute idea. We have doxies. Unfortunately, they ripped the apart in 5 minutes to get to the squeaker. I'm sure other breeds are more gentle with their toys. It would be a great toy for them.

Very durable
Pattern Name: Chipmunk
Our dog loves this "squeaky." He got it as a gift 11 months ago and I finally had to replace it because he almost had the head and tail chewed off -- took him about a year of chewing. I almost hated to throw the old one away because the squeakers still worked! Our dog is small -- about 22 lbs. -- but is a terrier mix and loves playing tug-of-war with this Zippy toy and he also loves shaking it like crazy. It's a great value compared to the toys I find in the local pet stores. Most of those "die" because he punctures them with his teeth so they no longer squeak. This one is well worth the price.

My big dogs FAVE!
Pattern Name: Chipmunk, Pattern Name: Chipmunk
These are the absolute best! We bought one in store over the holidays because they don’t have the stuffing that dogs like to pull out. My big dog thinks it’s his baby, but it’s light enough for my small dogs. As it got tattered from being carried, fetched, and bathed… we needed a replacement. He doesn’t do anything without his baby. He immediately took to this as it wasn’t brand new. Success with the replacement. I will definitely be buying again, because nobody one wants a sad pup.
