2016 GS Alternator and heated gear

I am considering a 2016 GS for 2 up riding with the wife. We both have Gerbing heated jackets and gloves. I am concerned that the 510W alternator may not have enough capacity to handle the bikes requirements and 2 sets of heated gear. Anybody have experience with the LC GS and running 2 sets of heated gear?

My wife and I have run two Gerbings jackets and had no issues with my '14 GSA's alternator. I think they draw 7 or eight amps each. Gloves (we have them but don't use them) draw less than 2 amps for each pair. I'd think you would be fine.

6 amps

I had similar concerns. I measured my jacket (alone) at 3.5 ohms, and (Jacket + heated gloves) at 2.4 ohms (in parallel with jacket.) [e.g., I (current) = v/r; = 14/2.4 = around 6 amps with both jacket and gloves; around 4 amps with just the jacket. Power = v[14v]*i, or 90 watts for jacket and gloves; around 60 watts with just a single jacket, if that helps your planning. Particularly if your 510w bike has LED lights should not be a problem.

I have 2016 R12GS--really love that heated gear!!!
