Package includes:
1x 4-Wire Regulator Rectifier

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.

Great for everyday use
We use these daily. I buy the complete set then boxes of each to refill. Very sturdy utensils. Size is perfect. Very easy to clean to use after dinner for deserts. Knives work very well and fork ends are sharp enough to stick in your food to eat. Only brand we use now.

Great quality!
These are every bit as good as the more expensive plastic ware. They’re thick and sturdy. I particularly like the cutouts in the handle. They’re easier for me to grip and keep ahold of. Extremely happy with this purchase.

Great product
Style: Standard, Size: 3 Count
Title: Good product, worth buying “I’m happy with this purchase. The product arrived on time and was easy to use. The quality is good for the price, and it works as expected. I’ve been using it for a few days and haven’t had any major issues. There are a couple of small things that could be improved, but overall it does the job well. I would recommend it to others looking for a reliable option.”

A must have for great tasting water
Style: Standard, Size: 6
These Brita filters are a staple in my house. They’re super easy to swap out and start working right away. The difference in water taste is noticeable—no more chlorine or odd aftertaste, just clean, fresh water. I love buying the multi-pack because it lasts for months and saves me from constantly reordering. Each filter holds up well and keeps the water consistently tasting great. It’s also a great alternative to bottled water, which saves money and cuts down on plastic use. Simple, reliable, and totally worth it!

Fast, quality filtration
Style: Standard, Size: 3 Count
Bought these for our Brita pitcher. Three in a pack is a good number for the price. They fit perfectly, as they should. No issues with leaking or clogging. We have pretty good water anyway but it's nice to run it through one more thing just to make sure. These work very quickly, especially compared to how I remember Britas working when I was a kid.
