Need more details. What upgrades do you have from stock in the electrical system? How do you mean it doesn't last more than 2 days? In storage? Running it ? How many starts/stops?My Kodiak can't last more than 2 days or so and the battery is dead. I had to buy an extender to stay charged. Is this normal? It's not even a year old.
maybe disconnect the hot wire on the winch and see if it continues to happen. maybe it's wired up incorrectly? i have aftermarket winch, it's hot all the time though... and i dont have any issues. can go a week without starting and it starts right up.nothing extreme at all. And the only accessory is a Warn Winch.
