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.

Arrived earlier than expected! Direct fit for my Piaggio X9 with no modifications needed. Great performance!
The updated circuit design handles voltage spikes better. My scooter's electrical system is finally stable after months of issues.
Very nice people with which to deal.
Perfect regulator rectifier for my CBR600RR! Fixed all my charging issues immediately. Build quality is excellent and it runs much cooler than OEM.
Great voltage regulator rectifier! High-quality build ensures steady power for my Polaris ATV, fitting perfectly and solving charging issues.

This product was exactly as described in the add.
The packaging was excellent. Lots of care went into this so nothing was damaged.
Great job 10/10 definitely recommend buying from them.

Packaged with care, arrived intact. Handles 30A load without issues. Great value for money!

Knowledgeable support team helped me compare OEM vs aftermarket options. The mirrors' aerodynamic shape matches the 929RR's lines beautifully. Top quality!

This big bore kit transformed my TRX400EX! The 89mm cylinder shows perfect machining marks and the piston rings seat beautifully. Noticeable power gain across all RPMs.

Installed in 10 minutes with basic tools. The gasket compresses evenly without tearing. Solved my intermittent charging problem completely.

This belt performs better than OEM on my Backcountry 850! Withstands deep powder riding without slipping. The reinforced fibers show no wear after 300 miles.

Safety Upgrade with a Super Easy Install. We always use the appropriate hand signals when riding in groups of 2 or more, but the added brake lights as well as turn signals are much appreciated by those riding behind me as I lead our groups more than most. I read the negatives comments about the adhesive, so I peeled the adhesive backing off, heated it with my heat gun and even heated the saddle bag a bit before mounting the lights and although it's early, it's been nasty hot, and the adhesive seems to be holding just fine!
The colors are a perfect match for the factory lighting on my bike!

Plug and play as advertised. This thing is awesome for the price!! Bike fired right up. No tuning or adjusting needed. I am very happy with it!!

Stator is well made and has put out consistent voltage.

Excellent parts, at a very good price

Installed flawlessly in my modified Charger. The 525LPH rating is accurate with consistent pressure under WOT. Anodized fittings resist corrosion better than stock components.

I purchased this item twice, once for the drivers side and again for the passengers side on my 2015 JKU. These rockers and lifters fit nicely and they look just like the parts from Mopar but at a fraction of the cost! I was able to use this set to replace all of the lifters and rockers and my jeep now doesn't tick! We've been around 1500 miles so far and the engine is much more quiet than before!

Tickking noise is gone!!!

I just installed these rockers and lifters and the tapping noise I had is gone. 2016 Jeep Wrangler 3.6. Couldn't be happier with the results. I will update if anything changes. I know what Mopar parts would have cost me and if these last half as long as the factory ones. I will still buy these again.

Perfect replacement at a great price. Love that it comes with starter and starter solenoid.
