How does the CDI work on the ignition coil?
In brief the CDI (ECU, Black Box, Ignitor) Grounds the Ignition coil which induces a spark at the plug. Assuming that the Ignition Coil/Coils have tested out OK then carry on…
What does it mean when your ignition coil is dead?
This is usually a sign that either the ignition coil is completely “dead,” that one or more electrical connections are faulty, or that you’ve done something wrong in your test. Carefully re-install the spark plug and re-connect its wire.
How can I test the CDI function of my car?
We can test this function by interrupting the circuit that runs to the CDI from the coil and bridging this with a Lamp which is rated at 12volt/3Watt located in a lamp holder. Crank (Hit the starter button) the engine and watch the lamp it should flicker on and off as the CDI makes and breaks the grounding circuit.
How is the resistance of a motorcycle ignition coil measured?
The resistance can be measured from the ground terminal wire or the primary wire. The primary wire is the one that is going towards the CDI points or CDI box. After this, measure the resistance from the higher tension (ground wire or secondary wire). The result for this should be higher around 7000 to 14000 ohms.
How does a GY6 150cc ignition coil work?
The CDI Unit is powered by the AC current coming from the wrapped stator winding. This current is stored in a capacitor within the CDI unit. When a signal is received by the trigger pickup passing over the flywheel magnet, the CDI will discharge the stored energy into the wires leading to the ignition coil.
What should spark reading be on ignition coil?
If your coil reads under 11.00, then chances are pretty good that this is the reason you’re not getting any spark or a very weak one. Replace the coil with a good quality new one, make sure you attach and tighten the leads correctly, plug in the top cable that goes to the distributor, turn the key and you should be good to go!
What should the resistance be on a Delco ignition coil?
This reading of 8.84 does indicate that the coil’s secondary windings are not putting out as much voltage as they should; the minimum acceptable resistance reading here should be 11.00, with approximately 13.5 being normal. Here’s the primary reading on the new replacement GM Delco coil before I installed it.
How to test and repair ignition system problems?
Place the appropriate shim between the rim of the flywheel and the ignition armature. While holding the shim, turn the flywheel until the magnets are directly adjacent to the armature
What happens if a Kawasaki ignition coil fails?
A failed coil will either read open or low. It is very unlikely that a coil will read higher than spec without simply being open. If the coil is in spec, then the wiring harness or CDI is likely at fault. QUOTE……..” Assuming that the Ignition Coil/Coils have tested out OK then carry on …:lol: “
What kind of ignition coil does Kawasaki KLE500 use?
The first picture shows one of the Ignition Coils on a brand new KLE500 i used for this Tutorial.
