Battery drain???

Ive got a new battery in the brute and if it sits for more than a couple days its only got enough charge to light up the display wont even try to crank. Any ideas what might be draining it so fast, its not a bad battery and it runs fine once its jumped or charged and then will hold a charge for that day but thats about it.

Test the voltage turned off and while running. It should be just under 14 volts...like 13.7 while running. If its 12.2 or less, its not charging.

What kind of ride and what do you have for accessories?

Could be a winch comntactor gone bad

Just because the battery is new doesn't mean it's a good battery. After you check what's mentioned above, I'd remove the battery, put a trickle charger on it overnight then let it sit for a day. Then take it back to where you bought it and have it tested.

I have that same problem on my 400 prarie. I'm pretty sure it has something to do with the winch. If I unhook the winch it doesn't drain the battery.

Normal/good winch should not be draining the battery when not in use.

I dont have any accessories running off the battery, no winch. And I had this same problem with the last battery I had also. I dont know it just drives me nuts that I have to pull the seat off and use a jump box everytime I go to ride. But like I said it will recharge and hold a charge for the day of riding...I only have to jump it when initially starting and can restart on its own all day but then a day or two later its dead again

If this is the second battery in that machine to do that, then you have something in the electrical system (somewhere) pulling power from it when you are not using it.
