Battery wires- black white and green

i bought a used 2015 starcraft ar-one and I go to install the battery and there are black, white, and green wires. I can see that white is the ground, so i hook that to the negative and from what i understand the black to the positive. The green wire has a fuse on it so i am under the impression that also goes on the positive. Can someone tell me what the green wire is for? what should all work with the battery hooked up? thanks.

If it's fused, it's a positive connection. Tongue jack, maybe?

Since it's used I would try and track it see where it goes may be something the previous owner had in it that no longer goes to anything.

You should check all the wires for continuity to frame ground. That will definitively expose the (-) phase wire to be connected. There is no answer to what the green wire is for as one would need to trace it to find what, if anything, it powers.

With the battery correctly connected your lights, fans, water pump, electric ignition water heater, and electric ignition furnace should all operate. You should also have a path of current to the onboard converter for charging. There should be a circuit breaker or fuse for the battery main cable within a few feet of the battery.

I would guess, the two wires from positive battery terminal are for 12 volt power supplied to the trailer, and power supplied to the break away switch.

You REALLY REALLY need to trace the wires to see where they go. On 12v systems, black is USUALLY negative, and green is not usually used.

Except on RV's, where white is usually ground and black is hot, to match up with the 120V systems.

Any color is probably connected to positive.
You can leave the green off until something does not work.

should the microwave or the AC work on the battery? thanks.

Could be a bad deal if it is the break-away cable.

It should be easy to follow the green wire to the break-away switch if that is it.

Neither. Battery is 12v DC. Microwave and A/C are 120v AC.
