What is CDI unit in scooter?
The CDI is like a computer as it controls the engine of your scooter. It instructs the fuel injectors when and for how long they should spray. It also directs the spark plugs on how to perform especially when they have to fire.
How does a DC CDI work on a scooter?
You have a DC CDI so it is energized by a black wire that comes from the battery, through the R/R, and then becomes hot when the key is turned on: OK, this gets a little tricky. The blue/yellow is indeed the trigger Harv, but it probably has a butt connector that changes to a white/black on it’s way to the CDI trigger port.
Why does a CDI unit need a capacitor?
CDI units, also known as Capacitor Discharge Ignition is the same electronic ignition system, but in place of using a coil and having the coil create its own spark, here the ignition is provided by the capacitor charge. The reason this is used is because the coils take a long time to collect charge…
How does a CDI unit work on a bike?
The principle that CDI units work in is a little bit complicated as there are a lot of parts involved which work in tandem but the overall process is very simple. There is a capacitor connected to a high voltage power source. Now bike batteries hardly come in 6 or 12V supply. So there is a need of a transformer to amplify the voltage.
Why does my CDI on my scooter go bad?
It also directs the spark plugs on how to perform especially when they have to fire. The CDI goes bad because of different reasons. Some of them go bad because they are old, others experience a wiring short while others go bad because of a faulty charging system. How is my CDI? The CDI in your scooter is linked to the ignition.
How does the CDI work on a scooter?
The CDI is like a computer as it controls the engine of your scooter. It instructs the fuel injectors when and for how long they should spray.
How can I tell if my scooter is AC or DC?
Turn the scooter key to the “On” position and, using a test meter or test light, check if there is current at the CDI. If there is 12 V at the CDI it is a DC CDI, if there is no voltage at the CDI it is an AC CDI. Similarly, is my moped AC or DC? To find out if your scooter is AC or DC is real easy.
Can a Honda scooter get an unrestricted CDI?
Tho, since performance of the stock 4-st Honda GET engine is very limited some people state different results. Don’t expect too much from installing an unrestricted CDI. Pretty much all of the Chinese 50cc scooters have a restricted CDI installed.
What does CDI stand for in ignition circuit?
What is CDI? CDI stands for capacitor discharge ignition (alternatively, “capacitive.”) If you’re new to capacitors, they’re similar to batteries in that they can store energy for later. What sets them apart is their ability to release all that energy near instantaneously, which is ideal for an ignition circuit. Here’s a CDI box in a dirt bike.
