I ride a 2013 F800GS. I have heated grips, sorta (as of late). I was riding a few days ago and they worked just fine, nice and toasty... Then at some point my I noticed my hands a little cold. On stage 2 they work as advertised, for stage 1. The grips are warm. On stage 1, with no gloves on, I can feel some warmth. Attached to the GS911, on stage 1 the 'heated grips' line on the PC app shows on/off cycling about every 1/2 second, stage 2 shows on steady. My question is, what would be the culprit of failure like this, they don't get hot anymore, just stage 1 warm on stage 2. GS911 doesn't report any failures. Thanks.
