Hey fam.

So the EXACT same thing happened to me as this guys post.
BV350 electrical gremlin

I was driving the scoot. I looked down and saw my instrument cluster was OFF. The bike was still running but ALL my electronics were off.
I pull off the road. Turn off the bike then tried to start it again.
I turn the key to start and no display lights or no electronic noise.
All I see is the Immobilizer LED flash once then stays off.

I disconnect the negative and check fuses. I see my #5 fuse blown.

Per my manual - fuse #5:

"Capacity: 10 A
Protected circuits: key powered: antitheft pre-installation, saddle release control unit pre-installation, turn indicator control device, high-beam flash, instrument panel, daylight running lights, horn, stop lights, start-up enabling switch, license plate light"

Trying to get bike to start/home I swapped the 5A fuse to my #5 10A slot.
I put the key in the ignition and the display turned on and did it's self check but then after 5 seconds it blew that fuse.
Now my brother has show up with more fuses for me.
I now have the correct 10A fuse and insert it.
It did the same and blew within 5 seconds.

Frustrated I test my luck and put in a 15A fuse In that 10A slot.
It worked!
The bike cycled on and started. I was able to drive it home.

Now here's my question:
Why did this happen??

Is it safe to run a 15A in the 10A slot?
I will buy more fuses today and try to put back the correct 10A fuse and see what happens.

That night I started the bike 3 more times without problems or blown fuses(but remember I have the 15A in the 10A slot)

Sides notes:
Reading the manual I found that if the Immobilizer LED flashes 1-3 times and STAYS on with NO start, then I have a fault.
But my led Flashed once with the key in then stays off.
So I don't think it's this problem.

The bike is a '13 with 1600 miles. The ONLY thing I did to it was replace the 2 brake light bulbs with brighter LEDs and I had removed my halogen cargo light(while I wait for my new LED cargo light to come in)
But since I replaced those bulbs and removed my cargo light I had driven it easily 60 miles with zero issue.

Sorry for the long post.
Can anyone help/lead me the right way.

I just had the same thing happen with my 2017 BV350 this fall.

Turns out there was a short in the license plate lamp assembly.

Had it replaced, problem solved.

In a word, no. Your fuse is blowing because something is drawing much more current than it should - probably some kind of short - you need to track it down to prevent creating a larger problem later.

berto: thx man. Do you think it has anything to do with my new led brake lights?

Monogodo: good info. I'm actually going to remove the rear section and license plate light. Hopefully that doesn't mess things up.

I think it might. As you've shown (good research, by the way), the brake lights are on the circuit that's blowing a fuse. And since you've recently changed something on that circuit, it seems worthwhile to double-check.

I would think LEDs should use quite a bit less current, but you could have something defective. Did you literally replace bulbs, or was there a new bulb holder unit or wiring involved at all? Do you still have the original bulbs to swap back in for testing?

How did you go about removing the cargo light? Is is possible you have a short there now?

Thx. Yea I hate not knowing things so I try and educate myself the most I can. Plus I couldn't find and answer online so I wanna share this with you guys

Just a simple bulb swapping.No new wires or accessories.
I do have the original bulbs. Ill try em out later

The cargo light is super easy. Its has an area to pry open with a small flat head. I'll pull that area and make sure nothings pinched. But I doubt it

When I first got my '13, it would blow the same fuse randomly. It turned out it was also brake light circuit related, as the PO had wired a brake light onto the topbox, and the wiring had worn through as it was pinched somewhere between the rear brake lights, the rack and the topbox.
