I think the PM on my chair is worn out, possibly. The R-net PM90 on my V6. Evey summer I go to this particular park with miles of horse trails, with many steep long climbs and descents. Lots of change in elevation. The trails always give my chair a workout. If I take the trails as fast as possible, the chair would overheat pretty quick on the terrain. But typically on these trails, I'm going pretty slow, no faster than pedestrian walking/hiking speed. And as long as I'm not in a hurry, I've can pretty much stay on the trails all afternoon, as long as I want.(at least since I converted to lithium)
At least I was till this year's visit. This summer I've noticed the chair cutting power and overheating on less steep trails with certainly less lengthy ascents. So I figured I might have a problem on the horse trails of this park. But my chair performed much worse than I anticipated. It was overheating w/ in 10 minutes of my first ascent. It was done and I had to leave the park for flatter terrain. If I did a long decent, the chair would not have been able to climb out, and I would have been stuck. It was a real bummer because its one of my favorite hikes to do in the summer.
Not saying I haven't put on a pound or two over previous years, but if I did, its been nothing dramatic. So I suspect the PM might need replaced. But what about the motors, could they be worn out too? Maybe they are not efficient as they used to be and are drawing more amps??? The chair is a 4-5yr old V6, and in all previous years, it handled this challenging hike like a champ. But this year, it barely made it out of the starting blocks before it was kaput.
