What do you need to know about CDI circuit?
Circuit Description Now let’s learn the CDI circuit operations in detail with the following points: Basically as the name suggest, ignition system in vehicles refers to the process in which the fuel mixture is ignited for initiating the engine and the drive mechanisms.
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.
How do you know if your ignition coil needs to be replaced?
Clip one end of the spark tester (service part number 19368) to the ignition cable and the other grounded to the cylinder head Spin the flywheel rapidly (at least 350 RPM) and watch for spark in the tester window If the spark jumps the tester gap, your ignition coil is working fine. If not, it needs to be replaced.
Is there a transistor controlled ignition ( TCI ) system?
Would be great to hear from someone who has done it. There are also 2 other pages dealing with basic electronic theory and batteries. The ‘82/`83 VISION has a ” Transistor Controlled Ignition” system ( “TCI” ).
How does the pick up coil on a CDI work?
All these events take place every revolution. Both the pick up coil and the power coil have two wires connected to them, one side of each goes to ground (usually coded black),they may be grounded internally in the magneto or connected together and brought out as a single wire and grounded outside or connected to a ground connection on the CDI unit.
How does shorting a CDI ignition system work?
Shorting either one to ground will disable the ignition and stop the engine,in the first case the storage cap does not get charged,in the second it does not get discharged.
Where does the DC current from an ignition coil come from?
A strong DC current pulse can be generated by a coil below the flywheel because the flywheel magnet goes over it. These DC current supplies throughout a wire toward an ignition coil placed at the external of the engine.
