Larger Battery for UTV??

[John_Mc]

I’m curious, did you direct connect to the battery? I did the same but I added a fuse block and ran mine through it. Problem is it will blow a 40 amp fuse if it gets very much load on the winch. I may have to move power directly to battery or put a inline fuse in that can accommodate a 50-60 amp fuse. Thoughts?

Even a small winch will pull a LOT of amps under full load. For example, the Harbor Freight Badlands ZXR 2500# winch pulls 132 amps at full load.

DO NOT put in a larger fuse -you may burn your wiring harness out of the machine. The lighter port/ ACC. Port is not made for the high current draw. If you look at larger quality onboard compressors for SxS/.Jeeps, they all have clamps for the battery and ditch the lighter port because of the amp draw. Same with a winch, they don't have lighter port plugs due to their current draw. Someone mentioned winches use surprisingly little power, but that is incorrect - they are one of the highest draw items on an SxS (for example, a 4000lbs Superwinch at 4000lbs pull is pulling 210amps - WAY more than a average factory SxS is producing). For example, A X3 Can-Am is putting out about 45 amps at 6000 RPM, Even a KRX1000, if you add an Alternator kit from the factory you only gain 60 more amps - still keeping you way below the 200 amps you need if you are winch yourself up a rock face. Thus why some of us run 2nd batteries - we need the cold cranking amps in reserve for heavy winching or in some cases guys need it to power their stereos and subwoofers as they suck some series power.

IF you have high current draw (amperage) devices one should add fuse block and fuse direct from battery using appropriate gauge wire...IF wire gets hot its tell you its to small of a gauge and the resistant in small gauge is to much for large amperage draw.... IF it blows fuse on internal circuitry that means current draw of device is more than electrical system is designed to handle, bugger fuse will only cause you more grief if internal wiring goes up in smoke...

My tractor has wired in a accessory power port limited to about 10 amps, got to respect that because tractor wire harness is to "light" to handle any thing bigger.....
IF I were to add a winch, first I would look at wire gauge on winch, THEN add system on tractor directly from battery with wire gauge that is same as on winch or recommended in winch manual (if wire not included)... Same goes for any device other the afore mentioned winch...
