'02 Adventure. Using the horn for a hot. It is off with ignition off. No relay. No fuse. Horn circuit is fused. No issues (except one grip is hotter than the other).
5 K miles experience.
Just got done with a 30-40 degree F. hell ride(Lake Superior) with the grips on high burn all the way. Warm hands even wet in a steady rain. Ran my heated vest too. Believe both consumers are 35 watts each for total of 70 watts. Battery voltage upon shutting down after 4-5 hours of riding was 12.05V initial, 12.02V after 4 hours. Not exactly good news since that reflects about a 30% charge on the battery. My drive-in basement is 63 degrees. The bike started easily after 5 hours without use, using full choke. Grips and vest off.
