Alcapone Posted January 3 Report Share Posted January 3 Hi, I would like to ask you if somebody has electrical values for checking of CDI unit, ignition stator motor, hall sensor and ignition coil. Somewhere is any issue and I need to eliminate step by step by each measurement. Quote Link to comment Share on other sites More sharing options...
lemur Posted January 3 Report Share Posted January 3 (edited) They don't appear to be very good with providing detailed technical documentation, do they. I always start at the source which is the alternator windings, you can meter test the alternator for resistance to confirm none of the coils is fried, resistance in the alternator coils will be very low and in the range of an ohm or two. Next is the regulator and rectifier which can be meter or oscilloscope tested for electric output only, the alternator needs to be outputting AC power on all leads to test the regulator output. Rectified power is only used on accessories like the fan and lights, has little to do with spark at the plug. The ignition has a trigger or pickup coil to initiate a spark and that can be meter tested for resistance. CDI can be tested using a second bike and swapping the parts to see if the problem goes to the other bike, virtually impossible to meter test much in the CDI unit, it's basically a power amplifier. Ignition coil, wire lead and plug cap can be meter tested for resistance in the windings or wires, the incoming side of the coil will have a lower resistance than the outgoing side and no continuity on either side of the coil means the coil is fried. Temperature sensors are easy to test and are covered in the documentation. Temp sensor is just a switch that goes from zero continuity to full continuity when the probe is heated. If you can't find the specs for your bike refer to a better manual that has a virtually identical wiring scheme as most 2-T trials bikes are the same when it comes to basic electrics. Biggest difference will be the models that are fuel injected because Fi models will have additional sensors, possibly a battery or large capacitor, plus a fuel pump that runs off DC electric.
