I had replaced my stock lamps with new lamps of the same wattage that provide much better illumination.
For those of you (like me) who thought you may have worked around this problem by installing separate fuses for each lamp- think again.
I have separate fuses (5A) and my big charging fuse blew again yesterday. Thankfully, I realized the problem and was able to avoid being stranded.
I had replaced my stock lamps with new lamps of the same wattage that provide much better illumination. Having also installed additional fuses on the leads to the aux lamps, I didn't take the time to go inside the new lamps and protectively wrap the internal wiring.
The leads to the halogen bulbs in both new lamps abraded through and was grounding out to the aluminum housing of the lamp (same problem as with the old lamps). However, the short was not direct enough to pop the individual 5A fuses. Instead, the added load of two nebulous shorts combined together to add enough extra load to blow the main 30A charging fuse!
I am now convinced that adding separate fuses on the aux lamps is not the best fix. I will wire a new separate circuit with its own individual fuse to the aux lamps to be trigger through a relay connected to one of the existing aux lamps leads. This is the same thing as the popular method of routing headlamp loads out of vintage stock handlebar switches by using a direct line to the battery in conjunction with a relay triggered by the old switches.
Installing this on the Stelvio aux lamps will totally remove the load of the lamps from the alternator charging circuit and eliminate the risk of blowing the main fuse that shuts down the alternator.
On top of this, I highly recommend that all Stelvio owners wrap their aux lamps internal wires with protective coatings. Special tape is available but I used Dymo label gun tape that I heated with a heat gun and then wrapped around the halogen bulb leads. On top off this, I recommend wrapping the wires with 3M double-sided trim tape that will allow the internal wires of the lamps to stick to the inside of their housings and not vibrate around so much.
I will report back later with pics.
Do you think there is any value in switching to low-draw LEDs in place of the 55W Hellas? Less draw, less potential load / main fuse issues? I am definitely going to change to LEDs for better lighting - I was going to wire them directly to the stock wiring since the draw is so low, but now I may go directly to the battery / fuse block with a relay (like I do with grips, Stebel horn, headlights, etc.).
I added large LED lights to mine. I used the factory wiring, and I installed a dimmer so that I can use them during the day without blinding people. The dimmer goes to 100% on high beam. They provide a LOT of light at night, and running them during the day gets me noticed. When the occasional moron starts to pull in front of me they get a blast of bright.

I got the Skene Design IQ-175. Uses the high beam to provide full power to the LEDs and the power level on low beam is programmable.HI Wayne.
I know this is an old post, but do you have any information on the dimmer system you used and the lights you used for LED fog lights?
I use aux lights on bike to be seen, not necessarily to see. The headlights on the Stelvio are stellar and don't really need additional lights to light up the road, however, the addition of aux lighting, especially in a triangular pattern, make you stand out on the road. To me, it is more defense than offense and would not ride without them.
Anyone had any issued with the bulb failure warning light coming on when replacing the aux lamps with LEDs? Just put ADVMonster Model 21s on mine and, although the new lights are great, the bulb failure warning light is now showing on the dash.
