Package includes:
1x Voltage Regulator

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.

CHOKING HAZARD
Flavor Name: Bone (S), Size: 6 Count (Pack of 1)
CHOKING HAZARD: I purchased these bones for my small Yorki.. He ate the first two without incident; however, on the third bone he unfortunately choked. As the bones wear down, they become extremely stringy, and those strands do not appear to be digestible. I had to rush my dog to the emergency room, which cost $700. Three days later, he became even sicker because he was unable to pass the remaining portion of the bone still in his stomach. I then had to take him to his regular veterinarian, where he was admitted overnight and diagnosed with pancreatitis and a severely irritated gastrointestinal tract. This entire ordeal cost me over $1,500 in addition to the initial $700 emergency visit. I am grateful that my dog is now alive and well, but these bones pose a serious choking hazard and do not digest properly. I strongly caution other pet owners, especially those with small dogs.

High-Quality Magnesium That’s Gentle and Effective
Size: 90 Count (Pack of 1)
This magnesium glycinate is easy to take and very gentle on the stomach compared to other forms. It absorbs well and is a great option for supporting relaxation, muscle comfort, and overall well-being. It’s especially helpful for easing tension and can support better sleep when taken regularly. Magnesium glycinate is known for its high absorption and calming effects without causing digestive upset. The capsules are a bit larger, but still manageable and worth it for the quality. Overall, a reliable and effective magnesium supplement.

Gentle Gentle Magnesium That Helped My Night Routine
Size: 90 Count (Pack of 1)
I bought the Thorne Magnesium Glycinate Capsules (90 servings) for $25 because I wanted a magnesium supplement that could support relaxation and better sleep as part of my nightly routine. I’ve been taking it for about a month and noticed I feel more relaxed in the evenings and wind down easier before bed. I also tend to get tension and poor sleep when I’m run down, so having magnesium in my routine has been helpful for overall balance. The capsules are easy to swallow and very gentle on the stomach, which I appreciate because some magnesium supplements can cause digestive discomfort. Magnesium glycinate is also known for being one of the more absorbable and well-tolerated forms of magnesium. I actually ran out for about a week while waiting for my reorder, and that’s when I realized how much I liked having it in my routine. Once I started taking it again, it quickly became part of my evening habit. The only downside is the price is higher than some other magnesium brands, but Thorne has a strong reputation for quality and third-party testing, which is why I chose it. Overall, this feels like a high-quality magnesium supplement and a good option if you’re looking for a gentle, easy-to-tolerate form of magnesium.

Superior Quality & Effective
Size: 90 Count (Pack of 1)
Thorne Magnesium is a total game changer! The quality is exceptional, and it has finally helped me get the restful sleep I've been missing. I’ve struggled with insomnia and tried numerous other brands to no avail, but Thorne is truly superior. It is absolutely worth the investment for results that actually work.
