I've got a 2008 Griz 700. I had the same problem a couple of years ago during an elk hunt. Turned out the stator fried due to the poor cooling design. New battery didn't last a day. Swapped it out and did the 2009 oil system mod and it has been running fine since then. I don't know if your model year has the same cooling problem or not. Worth looking into.

No issues with the Harbor Freight float charger. Been using it several years.

I bought some ratchet straps from them. They sent the wrong ones. Simple phone call had the correct ones on the way and I got to keep the wrong ones. I'd call that good customer service.
