one of 3 things bad coil, pickup, or cdi
To check the CDI (Capacitor Discharge Ignition) box on an ATV, first ensure the ATV is turned off and disconnect the battery for safety. Locate the CDI unit, which is usually found near the engine or under the seat, and inspect it for any visible signs of damage, such as cracks or corrosion. You can also use a multimeter to test the CDI's continuity and resistance according to the manufacturer's specifications. If the CDI appears faulty, it may need to be replaced.
No.
I just dealt with this problem on a motorcycle. I ended up taking it to the service department of a local dealer. They are equipped to run CDI tests; any reputable service/dealer will be honest with the diagnosis.
the only way to test a cdi is to repalce it. There is no other diagnostic for a cdi box
There are seven steps on how to check the CDI and the starter on a 200cc ATV. Some of the step-by-step instructions are turn the ATV off, use a voltmeter to get a reading on the battery, and then touch the black wire from your voltmeter to the black terminal on the battery.
it sounds kinda like a stator problem or spark plug or cdi box
first check your spark plug then test your ignition coil if these are good then it is probably the cdi but there is no way to test a cdi box.
yes it can be tested with a cdi tester!!! that even as a part number
You can not remove it, but you can change out the CDI box. http://www.magnumtuning.com/en/detail/revolution-pro-atv-speed-rev-limiter-cdi-box/john-deere/gator-xuv620efi/atv
the cdi is the igniton controll. this tells the engine certan things such as when to limit rpm and when to fire the spark along with the flywheel. some aftermarket companies make aftermarket cdi's that have a raised rev limit and a diffrent ignition map
tap on it with something then try starting it if it starts its the cdi box
