C) I have a 150cc Eagle scooter, I changed the core pack and the spark plug and I'm still not getting any fire to my plug and if it's my CDI unit how can I tell if it's bad? For what it's worth, this sounds more like a bad fuse box than a CDI, the fuse boxes on these bikes are known to develop cracks in the solder joints. If your vehicle is behaving erratically and you have problems with it running smoothly, it could be showing signs of ignition coil failure. Not sure about the CDI box. I've seen them cold start and idle fine and even accelerate but as soon as the bike warms up it sounds like Porky Pig. The CDI is not easy to diagnose because the observable symptoms of a faulty CDI box can lead to different directions. Every once in a while a guy has bad reeds causing a "miss" and thought that the stator was going bad. Symptoms of bad crank seals? so my trike was running fine one day and the next it would run until it warmed up and then just bog and die then you couldnt start it again till it cooled down. No spark to plugs. "AND NO CODES" Ohmd the stator and found #1 charge coil bad(4. Most electronic ignitions are not CDI, they just have a FET device switching the coil neg lead to ground (replaces the points job) with solid state circuitry to convert the hall effect sensor signal to switch the transistor on and off. I was out riding yesterday afternoon and it seemed the scooter was loosing power. ( 2-3) Remove the ignition coil IGNITION COIL PERFORMANCE TEST Test the ignition coil using a CDI tester. This unit will remove the factory rev-limiter and features a high output coil. We recommend adding the proper amount of the BlueDevil Head Gasket Sealer. If so, take the plug off, put a short piece of uninsulated wire into the connector where the plug fits, and hold the wire NEAR the fins (a millimeter or two). The switch comes in many variations with some turning lights off as it kills the engine. If the clearance got soo wide, you would lose a great amount of power because the engine would have a "bottleneck" and not be able to move enough air. On machines with charging systems you always want to check the output from the regulator. a. 344 lower than he said it should which was between 430-630. The capacitor simply charges and discharges within a fraction of time making it possible to create sparks CDIs are commonly found on motorbikes and scooters. Have a look at the HT lead condition they can crack up and this manifests itself at high reves. Crack the throttle and it would rev to about 4800 rpm, just enough to keep it moving. If the engine runs under a rich condition, the excess fuel will be expelled with the exhaust gases. Cylinders, engines, gaskets, magneto rotors I don't see a cdi on this scooter, the wire for the trigger signal at the coil is to the stator in line with kill switch. Symptoms. Excessive fuel consumption. Are the cdi units common to go bad on a 1992 wave runner III. a stator will make the engine cut out or give you no spark. Thus, inhibited engine ignition is a symptom. Failure to follow the above directions will void the warranty. I had this problem, took the spark plug out and held onto the end while kicking it over with my other hand, barely gave me a tingle. Are you sure this is an electrical problem? Pull that #2 plug and check if it's wet/fuel-fouled caused by bad fuel pump diaphragm causing raw fuel to get sucked into that cylinder. When the pole change occurs, the device sends a single, The capacitor simply charges and discharges within a fraction of time making it possible to create sparks CDIs are commonly found on motorbikes and scooters. 6 6. Here the ignition is provided by the capacitor charge. other than metering it the usual diagnostic of a cdi is to swap it for a known good-un . Looking from the front of the plug, you will see small metal tabs on each pin which secure them to the plug. Tuning by color is the more simple way to tune although in many cases, more risky. Rev Limiter + Tachometer 8. Using resistor spark plugs or boots will damage the CDI. KYMCO owners please note most of our CDI modules are AC. I did have spark on both cylinders but one was very weak. Symptoms of a bad ground can range from a completely dead bike to electrical components working intermittently. You check the reading coming out the stator with a multimeter. Our CDI modules are compatible with various versions of 50cc, and 150cc GY6/QMB139 4-stroke scooter engines as well as 50cc, 110cc, and 150cc Chinese made Honda-style 4-stroke scooter engines. Islander This post is not being displayed . check the CDI ground wire,it is located near the temp plug sensor,it come from the box side than goes to the right side of the carb's rack,mine was not a good one,and was always cutting off the engine under hard accaleration at WOT,taked mine time to find out,even after many jetting plug check. Pee more often than normal, or less often. So you’ve got a spark problem on your CDI-equipped motorcycle. this is my thinking: if it were the cdi, both cylinders would be misfiring right? so both plugs fouled right? BUT, what about the ign. I think something is shorted. How can you tell if the CDI is bad on a scooter? by Eric (Kinston N. Not feel like eating. symptoms of a bad cdi scooter
