I'm wondering about buying a friend of mine some grip heaters for his R75/5, but wondering if the stock charging system can handle the extra draw. Has anyone done this? I am not thinking OEM BMW heated grips, which were not available for the /5s, I'm thinking just basic stick-on heaters that go under the grips. In my experience these work fine. Current draw would be 2.5A on low and 3A on high. I believe the stock alternator is rated for 20A at 14V, so available power downstream from the RR will be a little less, but there's not much going on electrically anyway: A 35W headlight, 5W tail and the ignition system, which I don't know the power draw for. Blinkers, horn and brake light are inconsequential since they are only on briefly. Unless the ignition system draws a huge amount of power there should easily be an additional 3W in there I'd think, but I'd love to hear a yes/no from someone who's done it. Thanks.
