I don't ride the R3 much in winter because I have three other bigger bikes with better wind protection. But I decided to give the R# some exercise after she ahd sat idle 3 weeks. I hooked up my electric jacket liner with an adapter on the battery tender pigtail and had a nive 70 mile ride in the high 40s. Stopped near home to top of gas and forgot to turn off the liner, it was on low and I forgot I had it on. Only took 3 minutes to top her off but when I tried to start, it did nothing excepy the gauges went blank. With a push from a helpful local I got it fired but the guages were still blank and the speedometer needle would not move. I rode the 5 miles home and after a mile or so the guages came back but the check engine light came on. By the time I got home the light went out and all seemed normal. I put it on the battery tender for a few hours and disconnected. Multimeter said 12.6. I tried to start the next day and NADA, DEAD. It is the original on a 2015 R3 so maybe it was due for replacement but looking at the measlly 7AH rating I'd say it was never intended for powering a heated jacket liner. any recs on a replacement?
