The winch has by far the heaviest draw. I have a 5,000 pound winch on my Arctic Cat Diesel, LED'S and grip heaters. After an hour or so, the voltage will drop and LED's start to flicker. My solution is, stop plowing drive it until battery is fully charged. Mine has a small 45 amp alternator, don't know what the Stampede uses. I've thought about a bigger alternator, I already have a large Yellow Top battery. So, you can do like me, stop plowing until voltage comes back, maybe retrofit a bigger alternator(if you have a drive belt) fit a bigger deep cycle battery, or maybe a smaller winch, like a 2500 lb one. You dealer may be able to suggest.
