I recently installed some 10W LED driving lights on my 2007 to improve nighttime visibility, as well as how visible I am during the day. I wired them directly into the headlight low beam wires. They turned on and off with the bike, and everything was working well. After maybe 15-20 min of them being turned on with my trying to angle them and mount them into the correct orientation the bike suddenly turned off. It was completely dead, not a single light worked at all and it wouldn’t start. I traced the problem and one of the 2 main 20A side fuses were blown on the right side of the bike just under the seat. That is weird I thought, why would it happen after 20 min?
I replaced the fuse, checked to make sure there were no exposed wires/shorts and everything seemed good. The bike started right up and I was about 2 miles and 5 min into a ride and the bike died again. Uh-Oh. I checked the fuse and sure enough it was blown. I walked home and came back with some more fuses. I turned the headlight to the high beam (so my new additional lights wouldn’t be powered if that’s what was causing the issue), and this time the fuse popped in 2 seconds. I then disconnected the entire headlight assembly (so my wiring was not even connected to the bike at all). I tried with a new fuse and it popped in 1 second. I ended up walking the bike 2 miles all the way home
thankfully the route home didn’t have any hills and the bike aint too heavy to push.
After looking online it seems I have a short somewhere on the bike. Now I just have to figure out where. Any advice or things I could check to help me solve the problem?
10W of extra lights isnt too much for the power system is it? I also have an LED headlight and taillight, this should reduce the normal load on the system by a couple watts compared to an incandescent bulb. So overall I should be pulling about the same about of power compared to a stock bike.
Thanks in advance for any advice
