IT sounds like it is the pickups not working (.telling it to spark) if not then it will be CDI UNIT OR ENGINE GENERATOR COILS

SOURCE: No electrical power. The battery has a full charge. Main fuse is fine. What should I check next?

clean the battery terminals with a wire brush and tighten the connections up snug

I had the same problem 2001 XVS1100 Custom
this is a starter issue Over time the starter on this bike twists when its under a load.
Look at the two bolts holding the starter on if they are not straight across then its twisted. turn starter back in line with a pair of big channel locks and try to start this should do the trick if this works i would recommend taking the two bolts out and bend them back straight or replace and reinstall starter this should fixya problem

Hope this helps ...............Jimmyfixya

I am having exactly same problem. re starting, battery and fizzz. At the bottom of the carb on bikes left side is s screw. get a glass or old clean jam jar, place the thin tube in jar that comes off the bottom of carb, turn screw. petrol should start flowing into jar. let out about two egg cups full into jar. re tighten screw. hold jar up to light. what you have done is remove any water from the carb. you should see any water floating below the petrol. NEED I SAY DONT SMOKE WHEN DOING THIS . The fizz i cleaned all the contacts of any white deposits around bulb holders in the indicator arms.tightened the wiring conectors. Removed and dcleaned the indicator switch.

I had the same problem on my 2003 Kodiak. It ended up being the CDI Box. The Warn Winch was the cause. I had to replace the CDI Box on my twice before figuring out it had to do with the winch since it happened only after using it. I used the winch before when new and never had a problem.
