RUTU 4 Wire full wave Universal Voltage Regulator Rectifier Replacement - Boat Motor, Motorcycle, GY6 50 150cc Scooter, Moped, Go Kart, TAOTAO, ATV Rectifier- AC to DC Rectifier 12v Voltage Regulator

I have 2 of these and they both work great.I was able to use this and a super capacitor (ASIN: B08CGXJY2J) to add 12v power to my 196cc clone engine mini bike. You need to have the 2 coils under the flywheel (which you probably do if you have a headlight) and a 12v lead acid battery or a 16v super capacitor to make the power stable but it is a viable option to get a little power out of that anemic charging system. It will go to around 13.xx volts when off idle, but at idle only expect about 8v or so dc regulated. This is plenty good for my LEDs and horn.

Simple enough wiring diagram, works as intended.

Super

This unit looks like the real deal, but it is not. Perhaps limited to the one I received, but it does not output anywhere near the standard 14.5V DC. My setup has dual charging coils that output around 44 volts AC, which should be able to easily push 4 amps @ 14.5 volts out of this rectifier. It barely outputs 12 volts with zero load (battery disconnected). With battery connected the voltage is 12.73, entirely because that is the full charged voltage in the battery itself. And Yes, it is connected correctly and these readings are taken at full engine operating RPM. Again, it may be that I got a lemon, nevertheless it did not suit my application. Good luck

I have a Husqvarna riding mower that was failing to recharge the battery so got this universal voltage regulator. Failure of the engine to generate (about) 14v DC during operation could be a number of issues, some of them requiring more serious repair, but one of the quickest fixes is to change the voltage regulator. I did it with this and it worked for me.I cut the comes-with wired-on plastic clip off the device and went direct, wire to wire. Standard on these, you get 2 AC lines in from the magneto or flywheel (these are the yellow and white wires. As they are alternating current, it doesn’t matter in which order they go to the machine’s wires). Then you get one positive DC output (red) which goes to the + terminal on the battery. The green is the ground, which connects to the – terminal or to the frame. That’s it.

Works good does what it supposed too worth the money

It came with a very clear instruction.Keep in mind that some China engines may not have a pink wire. Instead, they might have 2 yellow wires (AC output from Engine), so you are safe to wire those 2 yellow wires to Pink and Yellow wires of the rectifier, the colors do not matter at this point.

Idk if this was defective or not. But in my case it didn't work to good. I hooked it up the way that it said to, still didn't have dc output, grabbed my meter and checked and had 3v on the output. Weird so I unhooked and tested to see if my input was too high and I may have fried it. On idle I got 24v ac and my painful holding of higher rpms got me about 48v ac. So not ove the 50v it says it can handle on the little paper in the box. So my best guess is mine wasn't fit to live. But for $12 it's not to big of a deal I guess. I had a bad experience with it so it's not for me.
