I have 1st Gear warm n safe . My first Jacket lasted 7 years of full time winter wear . It still works in the cheast but arms gave out . It , and the replacement jacket are 95 watt models . I recently dumped heated grips for heated glove liners that attach to my jacket . The liners are much better , and draw less power than the heated grips did on high . My Hayabusa has a volt meter installed that typically shows 14.1 to 14.2 VDC riding down the road with nothing on .
Jacket on medium drawing about 50 watts gauge shows 14.0 / 14.1 floats back n forth
Jacket on high power 13.9 vdc on gauge
Jacket / heated grips both on medium 13.8 vdc , and if it got cold I had to chose the jacket , and turn off grips.
Jacket / new glove liners everything on high 13.8 VDC run medium 14.0
All the above reading are with my LED 16 watt fog lights on full time ( 8 watts each ) No other accessorizes that draw power . Have deleted the 5 watt rear mud flap light , and changed all conventional bulbs to LED saving 35 or 40 watts . I'm going to go Cyclops head lights that will save 25 more watts , and give better lighting plug n play .
