I have checked the orange with white trace wires going to both coils and they are +ve 12v when ignition is on ..i think the right coil it is not being sent the signal from the cdi to ( NO. 2&3 cylinders) ..when i change the wires from one coil to the other i move the fault so i presume the coils are ok .. the plugs have been checked and they are ok but will need replaced at some point ..Q.is it the dreaded cdi ? do they usually fail on one side ? i have pretty much checked all wires for continuity and cleaned all plugs etc ... i have downloaded the wiring diagram and am learning about the loom etc ...the manual does not tell me what readings to expect from the digital igniter wires ..all it shows is the specialized suzuki box of tricks for testing them ! please help ! someone ..this is my only mode of transport and i am skint....
SOURCE: can't get any spark on rear left ignition coil
I didn't notice the year of the bike but
the orange wire comes directly from your TCI ignitor unit.
It might be a faulty pickup coil or the ignitor unit itself.
the pickup coils are in the right engine case and
have about 110 ohms resistance.
If there is no ohms reading on the pickup coil then
it is faulty.
If the pickup pulse coils are good then your
main ignitor unit is probably faulty.
Sometimes the solder joints can crack in them.
