You Really need a High Output Alternator And a 2nd Battery for a serious winch? Those LED off road lights aren't a serious load, but the amp draw on winches is Fierce! Wish I had a nickel for every jump needed by folks who thought just leaving the engine Idling was sufficient charging while winching out somebody else or themselves, then running back up 200' of cable? Especially where & when it's "Cold"? BTDT, & another thread I read earlier, I think in this forum, re: "JEGS, drop in battery tray & connections for Sequoias" where You still have to make up cables but adding 2nd batt. isn't a big deal. We have 2 8D's under/in bottom of ventilated tool box in bed(Tundra), & 2nd Type 27 on LC & High Output ALT is a Must. Isolator/switch is advised as well? You can kill a battery, multiple cells dead as doornails, when doing these connections, accidental contacts, etc. It does look like You got Your money's worth out of the original, if that's an '08? Batteries here (FL) are living on borrowed time after 3-4 yrs, swear.
