[QUOTE="dcarver, post: 1368029, member: 956"] I agree. I added the volt observation as I have a DL650 that had low charging voltage. The dealer replaced the stator and RR, no real improvements. The real problem was a failing fuel pump that was placing excessive load on the charging system. The wiring on the pump was intermittently shorting, then clearing, shorting, clearing. I saw similar voltage oscillations then as I do now. So of course my brain says it just *has* to be that issue again.. although I know better than to jump to conclusions without using systematic troubleshooting techniques. Fred, another possibility.. TPS. Didn't think of that. In both occurrences, I did not immediately attempt a restart. However, in both instances the cooling would have been slight. At Yosemite the offtime was ~5 minutes. Old Highway was more like 20 minutes. It is a denuded Cali model. No charcoal canisters.. Excess fuel goes straight to pavement. Previous experience watching the volt meter when fans kick on is a step-change high to lower but stable at the lower reading e.g. 14.2 to ~13.7 with a +/- .1 swing. This swing is much greater ~12 to ~14.2 vdc. It cranked strong on restart. KrZy8 has a 2 month old battery and fresh stator + RR. I see 14.3, 14.4 regularly now where as before max as ~13.5 unloaded. Regarding headlights... EasternBeaver makes kits to kill one light. I have that setup on a DL650 and it works great. I might consider doing the same for the 2013 FJR I'm farkling. Not that I could tell. I've never boiled before and I've been in much hotter weather. Tank bottom insulation is good and installed. [/QUOTE]
