Strange that you said you had voltage to the ignition switch as the left control switch supplies power to it and cuts power to everything when in the off position. Guess this control switch had an intermittent short in it. The charging rate is a little higher than normal,but see how it does for a few days.

It's still running today. Going to go ahead and mount up the plow, and throw a winch on it now. (Definitely keeping my snowblower in tip top shape, as I don't trust this four wheeler one bit.)
I am going to install one of the digital automotive volt meters, so I can keep a closer eye on it, while working the machine.
Thank you all for your help on this, really a big help. You guys have a lot of knowledge on these things, so thanks for sharing it with me.
I'll keep you posted on what breaks next.:nod:

Aw,come on be a little more positive.. :)

Just joking. I've been a Polaris fan for years. Haven't been on anything new, but my favorite has been a 04 sportsman 700 twin. Love the power that it has. Ride Polaris sleds as well.
This 450 will do exactly what I want it to now. Plow, and drag deer. Should last me a long time, now that i got the cluster to light up, it only has 600 miles on it.:D

Have you checked the voltage again? It should be charging around 14 volts when it's running, not 15.5.

Key on.

Running.

Looks good enough to me. 12 volt batteries are roughly 12.6 volts when they're fully charged. They have 6 cells that are 2.1 volts each, give or take a little. If it starts okay that's all that ever matters to me. The original 6 year(?) battery in my truck lasted 10 years but finally crapped out in the winter. Not enough cold cold cranking amps. My ATV is overdue for a new battery but I'm just keeping my eye on it for now. Sitting there not running for several months drained it and I haven't fully charged it yet. 14.4 volts while it's running is okay but it's toward the high end.
