Package Includes:
1x Voltage Regulator Rectifier

NOTE:
Before installing your new regulator rectifier;

Check the AC output of the stator.
Replace any burned or corroded connectors on stator and regulator/rectifier
Check and repair any melted wiring.
Use hi-temp dielectric grease on all connectors.

How to distinguish CDI box with AC fired or CDI box with DC fired?
If headlights turn on without the engine running(with just the key on), it is a DC system. In the AC system, turning headlights on require the engine to be running. Another indication is, if the engine will only runs with a battery it is DC. If it will runs without a battery, it is a AC system.

What does the voltage regulator do?
This regulator has the task of converting the alternating voltage (AC) generated by the alternator into the direct voltage (DC) 12V used in the vehicle electrical system and keeping the voltage within a certain range.
The voltage regulator is also responsible for ensuring that the battery is charged and that the light bulbs do not burn out.

How do I know if the charge regulator can be defective?
- Incandescent lamps burn out all the time.
- Headlights get brighter and darker.
- The battery is constantly empty.

Ergonomic Office Chair
Color: Nori Black (Pu Leather Seat), Color: Nori Black (Pu Leather Seat)
I’ve been using this ergonomic office chair for about a week now and honestly it’s one of the best upgrades I’ve made to my workspace. The chair was easy to assemble, feels very sturdy, and the mesh back keeps it breathable during long work sessions. The lumbar support is surprisingly comfortable and actually helps with posture, especially if you sit at a desk for hours every day. The seat cushion has the right balance of firmness and comfort, and I like that the armrests and height are adjustable to fit different setups. The wheels roll smoothly and the chair feels stable even when leaning back. Pros: ✔️ Comfortable for long hours ✔️ Great lumbar support ✔️ Breathable mesh back ✔️ Smooth rolling wheels ✔️ Modern clean look

Comfortable and Stylish Office Chair
Color: Cream Khaki (Pu Leather Seat), Color: Cream Khaki (Pu Leather Seat)
This office chair is comfortable, supportive, and looks great in my workspace. The adjustable lumbar support helps reduce back strain during long work sessions, and the flip-up armrests are convenient when I need extra space. The combination of PU leather and breathable mesh feels durable and comfortable. Assembly was straightforward, and the khaki color gives it a modern, professional look. Highly recommended for a home office

Just buy it and you will love it
Color: Khaki
Amazing chair. It looks as expected. Perfect fit for my needs. It has great lumbar support and value of my money. There is no squealing noise and pretty strong and sturdy. I am 5 feet and 8 inches and fits for me. Very easy to setup. I love that they have given extra and back up screwes for every component. Easy setup for one person and very easy setup for two people. I was able to set this up under 20 minutes. Screws and instructions are on the box and inside the seat package. Overall good purchase and happy customer and will update after couple of months.

A step up, but still room for improvement
Color: Cream Khaki (Pu Leather Seat)
Yikes, the *shilling* on the reviews for this thing! Yes, it's a chair. There are a lot of mesh-backed office chairs for sale here. None of them are likely to change your life. I can say this chair is a step up in quality from the few others I've purchased online in the past. All hardware below the seat cushion is heavy steel; you won't be breaking this stuff in the near future--and it's a nice change from the almost-entirely-plastic offerings I see elsewhere. The provided hardware was packaged intelligently: it's all screws (and not too many of them) with various lengths, but they all have the same size hex-head and the package includes a nice matching T-bar to install them; moreover, if you follow the instructions it's basically "use the screws labelled Step 1 now" then "use the screws labelled Step 2 now"--hard to get wrong. The best part of the chair is the lumbar support. It's why I selected this particular variant, and it was a good choice: it's firm and adjustable and makes a difference. The back is comfortable, and the general motion of the chair (rocking, locking, up/down, swivel, roll) is exactly as you'd expect. I don't like arms on my chairs: when they're down I rest my elbows there but they're always too high so it bothers my shoulders eventually, and when they're up my elbows bump into them. So I usually remove the arms entirely during assembly--and in this chair that wasn't too hard, but it does leave some slightly unsightly connection points hanging free. That's not a mark against the chair itself--just letting you know; at worst I could point out that this chair's arm movement is maybe a little more limited than usual. The worst thing about this chair, though, is the cushion. I got the leatherette seat, because it's supposed to be comfortable and easy to clean. In practice it's *not* comfortable at all: it's soft enough, sure, but it's also *very* hot and makes me squirm repeatedly to try to improve my comfort the longer I sit here. I suggest getting the mesh-bottom version, if you're going to get this model.
