CDI TROUBLESHOOTING
A series of diodes, SCR gate, and capacitor comprise the module circuitryA diode is solid state device desi current flow in one direction but prevents flow in the opposite directionA SCR gate is solid state electronic switching device which permits voltage to flow only after it has been triggered by another sourceThe ignition coil circuitry boosts the DC voltage instantly to approximate]y 20,000 voltsThis high voltage is passed on to the spark plugs through the high tension leads
