The missconceptions;
1) The bike runs without a clutch switch - the clutch switch simply alows the starter motor to turn the motor over .. ... if it stoped the motor - how would you change gear or stop at a set of stop lights ???
2) The rectifier will not stop the bike from running ... it charges the battery only.
-----------------------
Why won't the bike run? No spark.
There are two 'coils' that go to the CDI box from the engine - check both for continuity. Not unknown for these to go open circuit .. One coil supply the energy for the spark plug - the other coil tells the CDI box when to fire the spark plug. If you buy from Suzi then they come with the battery charging coils .. someone has rewound the spark energy type coil themselves over on Adventure Rider Motorcycle Forum and it is still working.
The third coil supplys the spark plug .. and should have continuity too ..
