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.

Absolute horrible quality
Color: Black, Size: Medium
Do not purchase this track suit even if its on sale. The fabric material is so cheap, it feels like a tacky uncomfortable plastic bottle that's been stretched out over your body. The stitching feels very off and the thickness is somehow too bulky and looks baggy and at the same time feels too tight. Do yourself a favor and avoid, I'm returning this product.

Solid 2pc set
Hubby recently had hip replacement surgery & needed some comfier clothes while he's recuperating. These are really comfy but they fit well and the subtle stripe just looks a little more "put together" than a standard sweat suit. This isn't his normal style but he's becoming a fan 🙂 Wash and dry well- no special treatment and no wrinkling or shrinkage. Warm but not hot, seem to be well made... not seeing pilling or strings unraveling, etc 👍👍
