I'm about to purchase the Gerbing heated clothing for this upcoming winter. I want the jacket liner, pants liner, socks and gloves along with the heat controller. I've added up the power draw and it comes up to 165 watts. I know that this is only at full blast, but I understand the alternator on my '05 is not exactly a powerhouse. Anybody have the Gerbing outfit? Any problems with power draw? I'd hate to end up with a dead battery during the middle of a ride. Thanks for your help.
