Package includes:
1x 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.

STELLAR Customer Service!
I only used mine about 10 times, and then the top somehow got stuck. I'm not that strong, so I don't know how it happened. Now I can't get it off and it renders it useless. There are no instructions that say whether it tightens to the right or left, so I don't know which way to direct my efforts. It seems to just get tighter no matter the direction I work it. UPDATE: The company immediately replied and offered to send me a new one, even though I bought it 2 years ago. This is excellent customer service! This brewer really makes life easier. Just don't screw the lid on too tight. It makes great cold brew, ready in the fridge when you want it. It cleans up so easily too!

love this!
So far I’m loving this cold brew kit in most every way. That said, I want to get the bad out of the way first: Even with careful attention to stirring the grounds my mesh filler was damaged within the first few brews. It’s just honestly disappointing because I love this kit to the fullest in every other way. It fits perfectly in my refrigerator door. The bumper at the bottom ring gives me peace of mind for protecting against the occasional bump. The filter, even with its weaknesses is well thought out. My brew is about how I like it after ~24+ hours of steeping. It has a convenient removable cap on the bottom to help remove used coffee grounds (your compost or worm bin will thank you!!!) The handle is comfortable and very convenient. I love the lid. It fits very very nice and snug and the design is very well thought out. Being able to pour my coffee without performing a juggling act is a relief. A simple turn of the lid and, “voila!” As a whole this cold brew maker is very attractive to use and store. It’s a mostly premium look and experience at what seems to be a competitive price at the time of my purchase. I will try to source glue to repair my filter and if that fails then look into a replacement from the company. EDIT: I was confident the company would reach out to me to make things right with an offer to replace my filter with their updated model. Have not heard back as of yet. Would certainly change my review back to 5* if they made this right. A product should not fail so soon - especially with the special care & attention I’d given it. EDIT2: Amanda and Justin were very quick to replace my filter once I found their email and messaged them my order number and explained my situation. 5 star product 5 star customer service.

Very good cold brewer.
This cold brew coffee maker is great. I was a little skeptical about it when I was shopping for one. But for such an inexpensive price and Amazon's great return policy, I would try it out. Well I'm glad I did! Even before it got to me, the seller sent me an email with some suggestions on how to cold brew and a pdf attachment with some nice recipes. I also bought a can of Cafe Du monde coffee to use with it. When it arrived, I went right in. I unboxed the brewer, and was really impressed with the quality of it. Very well made. The filter is strong and the removable rubber bottom of the carafe is a really good idea to make it non-slip. I like my coffee strong, so I filled the filter with coffee to the top. Especially if you are going to add ice later to your drink, make it strong. When your filter is halfway filled with coffee, fill the carafe with water halfway as well. Mix the coffee in the filter a little bit. Then fill the filter to the top with coffee and then fill with water. Give it another couple stirs and place in the fridge. When carrying to the fridge make sure to hold the bottom of the carafe. The handle is not as strong when filled with water. Come back the next day and stir some more. Later that day, or even the next day, your coffee is ready to go. I made Vietnamese coffee with mine. I put some sweetened condensed milk on the bottom of my glass ,with a splash of milk or half and half, then ice and cold coffee. AMAZING! Worth the wait. Not bitter, but not overly sweet either. Great taste with the cafe du monde coffee. Go get yourself one of these and enjoy. I am going to try the pumpkin spice one, that is in the recipe book the seller emailed me next. Can't wait!!!

Game-Changer for Cold Brew Lovers
This cold brew maker is so affordable and surprisingly amazing. I’ve stopped using my fancy Ninja machine—cold brew from this tastes so much better. It’s super convenient to have a full container ready in the fridge each morning, and it makes enough to last the whole week. Total game-changer!

Good cold brew maker…
Style: 1pcs 64oz black
Very much into cold brew now for several years and wanted to give this type of maker a try. Since I wasn’t sure if I would like it or not, I decided to go with the cheapest one and it was available with same-day delivery to boot! It is a winner! It is simple to use. Just fill the filter about 2/3 of the way full with coarse ground coffee and fill with water. You can let it sit in the refrigerator or on your countertop at room temperature. I think room temperature brews a little bit quicker. A very big plus is the metal mesh filter. It cleans and rinses off very easily. The lid and jar seem to be of excellent quality. I purchased the 64 ounce because I love my cold brew, but it is a little bit bulky and heavy for us senior citizens.
