ok i was going through my manual and it says my bike runs a transistor ignition.... but i have a single cdi box and run 2 coils. can you clear this up its like its contradicting itself.
What model bike and year? If it is CDI there will be a signal wire off of either the crank or stator. That goes to the CDI then the wires from the CDI go to the coils to tell them to fire. THere will be a ground wire too usually. CDI replaces your points.
90% of CDi igntions are basically electronic magnetos IE they are powerd directly from the generator and have no connection to the 12 volt system. There are a few out there that use inverters to ramp up the voltage, the very early Kawasaki H1 springs to mind - you can hear the inverter humming when you switch the ignition on. The one in my diagram is a classic example of an AC CDi fitted to hundreds of bikes and uses windings in the generator to provide the high voltage to charge the capacitor.
These systems have one feed wire from the box to the coil, if there is another one its earth. Both are dead with the ignition on bike not running. Don't try and measure these with the engine running - there is a series of 200 volt pulses firing the coil not a steady DC!
Transistor ignitions feed 12 volts to one side of the coil, the other goes to the TCi box. So both sides of the coil will appear live with the ignition on
It's an 85 Honda shadow vt500c I have three yellow wires coming off the stator but those connect to my reg/rec should there be another wire coming out of there also
Well don't I feel.dumb.....I've been going crazy looking for the pulse generator and never thought to look in the right crank case behind the clutch assembly....can a dyna ignition fit there
