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.

Cushiony and lightweight sneakers!
Size: 5.5 Toddler, Color: Gold/Rainbow, Size: 5.5 Toddler, Color: Gold/Rainbow
The shoes are excellent quality! I was worried that the soles would be heavy since they are a little thicker than other toddler shoes, but this is not the case. The shoes are lightweight and run true to size. They were a little hard to put on the first two times and I thought, "Oh no, they must be too narrow." However, after my toddler wore these for a few hours each time, they stretched out and I checked her feet and did not notice any signs of discomfort, such as impressions on her feet from the shoes and/or redness. Toddler walked "normal" and even ran in these. The style is supercute (gotta love the subtle sparkles) and athletic and they appear to give her a lot of support. I can't speak to durability as she has only worn them for a few weeks but so far, they held up well and I have no issues with the velcro. I am glad they softened and stretched out after a short time of wear and they have plenty of cushion! Overall, these are great and no complaints here. I highly recommend!

Great looks for any outfit choice
Size: 12 Toddler, Color: Black/Grey
I was proud to see my first grader run their first mile on these shoes. The look and color is great for either a boy or a girl, and matches with either neutral colored or bright outfits. My kiddo found it easy to put on and adjust snuggly, so it’s nice having a shoe that doesn’t require an adult to calibrate and tighten just right (like my kids soccer cleats!). This is several steps past your cheap sneaker and I can tell it will comfortably get many more miles from my kid.

A good choice
Size: 4 Toddler, Color: Black/Grey
This is a great pair of shoes with excellent durability and color. It’s a classy little shoe that looks good and had a good fit. That was true to it sizing. It’s an excellent value for the money and they held up well throughout testing. No flaws were found in any of the materials and workmanship was phenomenal. If I could give it more than five stars I would.
