grounding wire?

[Yukonman]

After winter storage I was putting the batteries back into the trailer.

I connected a white wire from meh to neg
Black wire pos to pos
I was about to connect pos from trailer to one battery, and neg to the other battery when i found this orange wire.

Is this a grounding wire? And if so should i connect it to the battery neg?

Generally, only the white wire should be connected to the negative battery terminal. That orange wire is probably the positive feed for your jack or brakes, but it could be anything.

It's always a good idea to tape all the positive wires together. My last TT had 5 positive wires of various colors. But just 1 white ground lead.

My present trailer has 1 black wire for ground, 1 red wire for positive. Go figure...

So I had a long drawn out experience here.

I decided that I would assume that orange cord is the jack cord and I wrapped it around the positive post. Using a hex nut I began to tighten it down, hand tightening until I couldn't anymore.

I then grabbed a socket wrench and began to tighten, Sadly after a few turns I realized the post was turning not the nut.

I tried to reverse it and couldn't

I was forced to use my dremmel moto tool to cut the nut off the post destroying the nut and post..

I am now using 1 battery instead of 2 in parallel.

But the orange cord didn't blow up my trailer... whew.

On another note, I can still use the other battery as a nut will still go on flush with top of post where it got stuck. I am going to get some washers to push down the wires and keep going.

Lessons learned.

Connect the two using a regular battery cable from any auto parts store.
