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.

Game-Changer for My Space!
Color: White, Size: 4 Panel Basic
I recently purchased the Kecreque 4-Panel Room Divider, and it has completely transformed my living area. At 88" wide, it provides ample coverage, creating a private nook in my open-concept home. The white polyester fabric is not only sleek and modern but also wrinkle-resistant and easy to clean—just a quick wipe with a damp cloth, and it looks brand new. Assembly was a breeze; I had it set up in about 20 minutes. The metal frame feels sturdy and durable, and the three extra-wide metal feet offer excellent stability, ensuring it doesn't tip over easily. I love how the panels are connected with flexible buckles, allowing me to adjust the configuration to suit my needs—be it a straight line or an angled setup. This divider has been perfect for creating a dressing area in my bedroom, and I've also used it to section off a workspace in my living room. Its versatility is unmatched, and it folds down compactly when not in use, making storage hassle-free. If you're looking for a stylish, functional, and easy-to-use room divider, I highly recommend this one. It's been a fantastic addition to my home!

Sturdy and Functional
Color: White, Size: 4 Panel Basic
I got this to replace a poor quality divider that I tried first, and this thing is the best! It is easily folded, stands sturdily, easy to assemble, and the fabric looks great. Very very happy with the quality for the price.

Arrived damaged
Color: Black, Size: 4 Panel Basic
Unfortunately, very cheaply made. It arrived with one of the connecting tubes cracked horizontally. Possibly due to bad welding. It is quite a headache to assemble. It was delivered on time but returned for a refund.

Not a great experience but a fine product
Color: Black, Size: 4 Panel Basic
not enough screws were included to make the wall. I was able to locate more screws to finish building-so I didn’t have to return the product- but it was a pain and I got lucky finding the pieces I needed but it could’ve been a fail and a returned product

Useful, simple room divider
Color: White, Size: 4 Panel Basic
All the pieces were accounted for, and some even had extra pieces, maybe just in case they need changing. It was a bit like putting together a piece of IKEA furniture, though I went slower than usual so as not to make any mistakes. It wasn’t too hard to put together myself, and helps give my studio apt a feeling of space and privacy for my bed. I only wish it had a lovely Japanese design on it, but it does amazingly seem to match the wall color.
