I took a ride up a mountain pass yesterday and took the opportunity to use my new heated chaps. I have a Synergy jacket and gloves as well (left the gloves out on this ride). The heated clothing would only stay "lit" for a few minutes at a time. I have Yamaha Driving lights and I turned those off, then the sysem worked great. Based on earlier math, examples and people much brighter than me, I shouldn't have had a problem. I just replaced my battery this August so don't think this is an issue. The bike is a 2008 and the only other electrical mod is an LED turn signal light bar under the stock stop light.
Jacket - 76W/6.3A
Chaps - 43W/3.5A
Gloves - 24W/2.7A
Lamps - 70W (based on two 35W halogen bulbs)
The Synergy pigtail is hooked directly to the battery with a 15A inline fuse so is similar to earlier quoted work.....any thoughts?
