That's what i'll do, but I would have liked to get an idea of the problem, so it won't happen as soon as I restart the bike. Thanks for your help mates!

I wish I could see the harness, but I can't all I would do now is repair it and put it back. No need to replace a whole harness for a couple of damaged wires.

The main fuse, yes. The problem is that the supply to the main fuse is not fuse protected. Cars use a thing called a fuseable link which is just a wire that is designed to melt and protect the rest of the main harness

But the melt down happened on the front accessory wire, so between the fuse box and the accesory, not the fuse box and the battery, so the 10a fuse shoud have taken the blow, not the wire. What could have happen so the fuse did'nt blow, but made the wire melt?

every fuse has 2 sides. load and supply. The fuse protects the load side, the main fuse protects the supply side

I understand, but normally if the supply side of the fuse has a short circuit, the extra load on the wire should burn the fuse before the wire melt, no?

By the way the front accessory that blew up is on a fuse of it's own, so no need for an auxiliary box. It most go trough the main switch so trough the 30a fuse.

I'm certainly not the first one to run a trailer with a drifter 800. The only additional load is the light bar, and I been running it for two years without any problem. I think that maybe the two problem are two separate thing that happen together but not necessarly related. Maybe the system was temporairly overload when the main fuse blew. But I dont see why it would only melt the front accesory wire? When the wire melted the fuse box was hanging on the side of the frame when I started the bike to test the main fuse, so it might have shorted there. But if the short happened there would'nt the wire be only melted between the fuse box and the short? The other thing that puzzles me is tha the 10a fuse did'nt blew, after the melt the fuse was still fine? Any explanation why? It should have blown and left the wire Ok? How come it did'nt?

You added way more electrical load to the bike than it was designed to handle. Troll's recommendations are right on.

You have the harness out, right now. Unwrap it and trace any wires/separate any that melted together. Insulate them and/or replace them with new wire, if the insulation is breached. Sounds like something shorted to ground on the supply side to your accessories. Don't over load the individual stock wiring circuits. You would be much better off installing an aux. fuse box to handle extra loads. Once you have repaired the harness, and it's reinstalled, add things one at a time, making sure there are no shorts to ground

not sure if this helps but found this and now I am wondering if I am reading it correctly.

Wait for Troll to explain all this electrical stuff and educate us ....

Everything went fine with all the lighting, the trailer and the iphone, for about two weeks the problem just appeared when i plugged the sena for charging....maximum 5-10 watts draw. Then the rest is a cascading effect from that event!

...sounds like the mighty Troll needs to weigh in here. This is right up his alley. Just sayin'......
