Answer 1

Testing the system is similar to any dirt bike or Jet Ski but I don't have a manual for yours. You can test the generating and trigger coil with an ohm and volt meter. The igniter is a whole other matter. Sometimes it's cheaper to take to a dealer as there are no returns on electrical parts. Flatrate is .9 hours to test and repair the ignition system.

Answer 2

Check the simple stuff first like new plugs and missing or broken ground wires. The battery, electrical case and engine all have to be grounded to work. Also check your wiring on the bars for a broken kill switch wire. Check for burned or bare wires in the engine compartment. The fuse you see should be for the regulator. Change it if it's bad.

Your ignition system uses a generator with a trigger coil. Voltage and the triggering signal go to the igniter then to the secondary coils and to the plugs. Any of those items could be bad, or wiring or switches.

When was the last time it worked and what happened when it quit working? Did it get flooded? Was it just worked on? Did it overheat?
