This usually means there is a current Diagnostic Trouble Code (DTC) is present. Check your manual for how to access and reset the DTC.

I was riding my bike running great went to store turned off the key when i turned the key back on no power to the lights or instrument panel. i checked all fuses. it has good battery. i arced the starter...

Locate wire block at ignition switch, using a test light or multimeter check red wire for 12 volts dc, if you have no voltage here, you will have to trace the wire back to the battery and fusebox some models have a circuit breaker on the underside of the battery box, or in the imidiate area, its a 2 wire breaker with a transparrent cover and a red dot in the centre, push at this point to reset, have you checked the fuse at the solenoide 30 amp, if you do have power at the red, turn the ignition switch to the park position as the bike has a seperate live to the rear light, it should light(this will also proove you have power at the ignition)

Red key shaped light flashing on speedometer

The red key indicator is to do with your security system. When you turn the ignition on and put the handlebar control to the "RUN" position, power is applied to the fuel pump inside the fuel tank, that is probably the sound you are hearing.

The red key indicator usually flashes to show that the system is armed.

If you have a problem the only way to really find out whats going on is to have a dealer check the bike for trouble codes, this is usually done by connecting a computer to the data plug on your bike (this connector is usually found under the seat near the battery).

Hope some of this helped.
