I'm currently installing grip-heaters on my bike, but i got no clue what so ever on the electrical part. So i really have 2 questions; 1. Im connecting the swithc directly onto the battery, so what fuse should i use between ( strengh of it). 2. Will i survive tuching both plus and minus on the battery when the ignition is off? <--- that scares me o.O I'v gotten some badass shocks in my life doing less complicated electrical stuff. If anyones interested i can snap some shots of how iv done it.
