Had it happen to my Nightfire a couple years ago. Sometimes it is caused by a pinned/shorted wire going to the taillight. Replaced the fuse on mine and it has never blown again; never did check for a short.

Check the blue 15A fuse under the hood up by the wire harness/ECU/CCU/hood cable on the right hand side. It's in a little fuse holder that looks like this...

fuse was fine lights work at idle then go out on throttle friend said lights would flicker on the trail do you know what ccu is bad ground maybe thanks

From the service manual...

The CCU performs two important functions on the
snowmobile. Its main function is to distribute regulated
DC power to the chassis electrical systems. Its
other function is to control the forward/reverse shifting
of the ACT drive to ensure safe operation.

The CCU has two DC outputs used for lighting circuits.
Both outputs have a circuit breaker (self resetting
devices) which protects components from overcurrent
and short circuit situations. If a system stops
working, it is likely a short has occurred and the system
has shut itself off much like a fuse will blow if a
circuit is shorted to ground. However, unlike a fuse if
the short is resolved, the CCU will reset the output and​

the system will return to normal operation.

The first output, labeled the High Power DC Output,
supplies power for the headlights and handwarmers.
This output is on only while the engine is running.
This output is turned off during shifting to allow maximum
power transfer to the ACT drive.
The second output, labeled the Low Power DC Output,
supplies power to the gauge, speed sensor, taillight,
accessory plugs, and APV servomotor via the Engine
Control Unit. This output is on only while the engine is​

running. It is not turned off during shifting.

it didnt have a number behind it it just flashed ccu awesome info thanks a ton i didnt count the flashes ill dig into it sunday i read some older posts and some said that water can get in the connections which would make sense yesterday the powder at snowy range was about 3-4 ft deep anyway thanks again

fixed

i have a speedwerx tunnel dump pipe and you have to relocate the reverse beeper my zip ties broke and melted the wires together repaired this and all is good
