In the midst of my Colorado tour a couple weeks ago my '09 VFR's battery died. This was atop Grand Mesa about halfway between Grand Junction and Delta, an hour away from either. Luckily it bump-started and got me to Delta and our motel for the night. We found a local shop, Fast Repair, and the battery measured 12.0 volts engine off, and about 12.7 running. The three phase plug from the stator measured ~40 vac on two coils but only ~16 on the third. In retrospect the stator was the obvious fault but throwing parts at a problem when you're 1,000 miles from home gets expensive. So I disconnected the wiring for my electric vest and grip heaters, and also pulled the headlight fuse. Since the bike had run fine on a flat battery for 80 km, I figured a new battery might let me finish the trip. The recharged original added some peace of mind. If worse came to worse I'd rent a truck and haul it home.
There was no trouble on the next three days, but on the fourth it died again so I swapped batteries at the next gas stop. The next day I bought a small charger & multimeter and that was enough to get me home.
Today I picked it up after my dear installed a shiny new stator. Not a cheap fix but one of the few hard faults I've had over the past 25 years.
