I've been having a problem with bike since few weeks- it was cutting off suddenly occasionally but still ran, until few days since when it just doesn't start
There is no spark to any of the plugs. I checked by putting a screw driver in the leads(as it is a pain to remove the plugs) and position it very close to the engine while cranking and no sign of spark at all...
I used the manual to do some ignition checks:
I measured the voltage on the CDI 6P(to ensure no faulty switch on the loom) connector and resistance of the ignition primary coil and all of this is normal.
I get a resistance of 3.4 ohms at the primary coil terminals and 14kohms at the secondary coil terminals.
I also checked the resistance of the pulse generator and getting a 540ohms between the wires and 0hms between any of the terminals and the ground which according to the manual is fine.
Everything is leading towards a faulty CDI... Any other suggestions will be appreciated.
I read somewhere before that a fault fuel pump relay could "simulate" fault CDI somehow- didn't make any sense to me but dunno - can anyone think of something?
Also someone else mentioned about a diode in the ignition switch fault - any explanation about this as well?
Please recommend something, as I really hope to not have to buy a new expensive CDI?
