What do you need to know about CDI wiring?
For the time being leave this disconnected. Black/white wire – To the ignition/kill switch (You are correct in saying connecting this to the earth will prevent the ignition coil from sparking. The bike will still start if you dont connect this wire but you will need to stall the engine to cut it out)
Where does the spark plug go on a CDI?
The ignition coil (connected to the spark plug) is attached to the frame and seems to make an earth connection to the frame itself. I ran an extra cable from one of the holding screws to be an “earth point” for all my earth connection.
Do you need battery to run CDI ignition?
Connct the black/white to the green to see if oyu get a spark. Another thing to consider is some cdi ignition systems are designed to be run from d/c others a/c, you may well need the battery to make the bike run. Some people are only alive cos its against the law to kill them.
Can a 4 wire CDI be connected to an earth wire?
On a 4 wire CDI it would be connected to the CDI – Kill-switch should be connected yes/no and to the Red or the earth wire? Anyone has any advice for me on what to do next, OR has a Honda GL 150cc wiring diagram for me? Thanks in advance for all the help! This post is not being displayed .
What do you need to wire an ignition switch?
Wiring an ignition switch involves locating the ignition switch, identifying the pins, disconnecting the negative battery cable, connecting the lead wire to the ACC terminal, connecting the relay wire to the ST terminal, connecting the ignition wire to the IGN terminal and reconnecting the negative battery cable.
Where is the starter relay wire on a ignition switch?
The starter relay wire needs to be connected to the Start terminal located on the ignition switch. The final step is connecting the ignition wire to the ignition terminal located on the ignition switch.
Where are the terminals on an ignition switch?
The back of the ignition switch has four terminals, which are the Battery, Start, Ignition and Accessory. The procedure for wiring an ignition switch is as follows: To begin with, the negative battery terminal must be disconnected before locating the positive power lead to the switch.
When do you need to replace the ignition switch?
Replacement of the ignition switch becomes necessary when you have trouble turning on the electrical system, or if the starter fails to stop turning after the motor has started.
Where does the CDI cable come from on a bike?
Can’t make a picture of that now, as it’s under the gastank. From this unit (besides the new extra line I made) there are two cables, a Black/yellow and a full-green. Both directly run to the CDI (using the original cable and plug). : and a red/black, which also comes from the engine block.
For the time being leave this disconnected. Black/white wire – To the ignition/kill switch (You are correct in saying connecting this to the earth will prevent the ignition coil from sparking.

What does a CDI box do on a dirt bike?
Here’s a CDI box in a dirt bike. You’ll often find them lurking under your seat. Andy Greaser photo. The basic CDI system is a trigger mechanism, coils, and a box, often black, with capacitors and other circuitry inside. The trigger tells the box to fire, the box determines when to fire which coil with the capacitors,…
Why is my CDI not working on my bike?
The problem may get worse as the bike warms up. It might not even hold low revs at all. You’ve tested everything but the CDI unit, including the charge of your battery, your spark plugs, the health of your coils, and the triggering mechanism itself. Could it be your black box?
What does CDI stand for in a battery?
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 to do if your Polaris ATV won’t start?
now….. 1*. Check the spark plug to make sure it is firing.. remove the spark plug.. make sure you have metal to metal contact and then turn the engine over.. (this might be a two man job).. the spark plug should have a nice big blue white spark,, (some electronic’s will have a weak orange and still fire fine!) 2.
Can a motorcycle be wired for a Dummies?
Motorcycle wiring for dummies: Keep it simple! Cape Town – It sounds familiar, because it’s happened to all of us. Your motorcycle doesn’t have a specific problem, it just won’t crank over hard enough to start and if you push-start it, the dashboard lights go dim and flicker when it’s idling. OK, let’s keep it simple.

What does black dot mean on CDI wiring diagram?
All of it rides on circuit that’s being constructed. According to previous, the traces at a 6 Pin Cdi Box Wiring Diagram represents wires. Sometimes, the wires will cross. However, it doesn’t imply connection between the wires. Injunction of two wires is generally indicated by black dot on the junction of 2 lines.
What are the components of a CDI box?
The most common components are capacitor, resistor, and battery. There are also other elements like floor, switch, engine, and inductor. All of it rides on circuit that’s being constructed. According to previous, the traces at a 6 Pin Cdi Box Wiring Diagram represents wires. Sometimes, the wires will cross.

How does a capacitive discharge ignition ( CDI ) circuit work?
The basic working of a CDI unit is executed through the following steps: Two voltage inputs are fed to the electronic CDI system, one is high voltage from the alternator in the range of 100 V to 200 V AC, other is a low pulse voltage from a pickup coil in the range of 10 V to 12 V AC.
Can a 5 pin CDI work on a DC bike?
The 5 pin CDI is an AC unit, intended to work on bikes where the CDI is powered by an AC coil within the stator. The 6 pin type are for DC systems, where the CDI is powered from a battery. As long as you have the right one (AC or DC), and its wired correctly these units will work on almost all bikes.
What happens when you turn off the CDI on a motor?
When we want to shut down the motor engine, we have two switches the key switch or the kill switch. The switches ground out the charging circuit so the entire charging pulse is sent to the ground. Since the CDI can no longer charge, it will cease to provide the spark and the engine will slow to a stop.
How does a CDI ignition system work on a bike?
The keyway on the magnet is offset to the poles of the magnet. Maybe putting it on backwards cause the sparkplug to spark somewhere other than close to top dead center of the piston. I pulled the magnet off, turned it around and put it back on. EUREKA! Bike fired right up and runs like a dream.

What kind of coil does a CDI use?
These systems generally use a higher resistance type coil and are known as an “induction” or “Kettering” ignition systems. CDI sends a brief high (200+) voltage pulse to an uncharged coil which act like a transformer and multiplies it even higher.
What does the trigger on a CDI box do?
The trigger tells the box to fire, the box determines when to fire which coil with the capacitors, and zap goes the spark plug, ad infinitum. In addition to dischargin’ those capacitors, the box may also influence your rev limit, timing advance, and other variables related to spark, but that’s it.

How can I tell if my CDI machine is AC or DC?
Most machines (especially the newer they are) are AC. DC CDI boxes are larger than AC CDI boxes. The easiest way to tell if your machine is AC or DC is to turn on the headlights with the machine turned off and the ignition in the “ON” position. If the headlight comes on, it is a DC machine; if it does not, it is an AC machine.
Where does the CDI box amplify the signal?
The box amplifies the small signal generated from the spinning magnet located in front of the pickup coil in the stator, just before top dead center (TDC), when your fuel-air mixture is ignited. The box can’t generate continuous sparks.
