The cable is connected correctly, but no fire from spark plug. Checking more detail, it seems not even any output voltage from the CDI, if it works there will be a voltage from inverter and fill the Capacitor, but there is no voltage at all, my assumption, the inverter did not work. Even with a simple check, the CDI does not sound any activities at all 😀 usually if the CDI works, the inverter will sound some oscillations.
The interim analysis, the work of CDI Jupiter is determined by certain conditions, there may be a kind of switch in the circuit. And again, according to bintangracingteam , Jupiter has a digital CDI so that makes it more plausible. CDI Jupiter has three conditions, low rpm, moderate, and high where the conditions for high rpm, the timing actually shrinking. This means that Jupiter CDI is designed for low to medium rpm.
Yamaha Jupiter-Z, at 1500 rpm up to 2,500 plugs snap of 15 degrees before TDC (Top Dead Center). From rpm 2500-3500 Ignition timing 32 degrees before TDC. further to 8,000 rpm is 32 degrees. More than 8000 rpm down to 30 degrees before TDC
Temporary conclusion, CDI Jupiter requires a certain input conditions so that the CDI is able to work. Might use the detection of voltage pulser, another possibility could be to use detection form large pulser signals, such as duration. While this is all I can conclude for now, until I had a chance to disassemble CDI jupiter 😀 Probably somebody from Yamaha or Denso wants to give some input 😀
