Question What is this gizmo on my battery?

I'm preparing to completely rewire my '80 Scamp, install new marker and taillights. I'm making a diagram of the complete system (similiar to the Scamp diagram, except it includes battery, my particular appliances, breakaway switch, and the original Scamp color wiring.). The RV dealer in California, where I purchased the trailer, installed the battery and got the lights working so I could tow it back to Oregon. He installed a two-post device between the battery terminals that they are connected to. What is this device, and what is its purpose?

What is this gizmo on my battery?

I'm completely rewiring. '80 Scamp this winter. I'm making a wiring diagram similar to the Scamp one, except it includes my the battery, trailer side plug, breakaway switch, my own particular appliances, etc..)
The RV dealership that installed my battery and got the lights working so I could tow it back to Oregon installed a cigarettepack size device that has two terminals, and is connected to the battery terminals. Can anyone tell me what this is, and its purpose? Thanks.

It looks to me like you attempted to draw a wing nut for each battery post. It is typical in RVs to use wing nuts rather than battery post clamps. The smaller (10 to 30 )amps that an RV draws doesn't require the larger contact area a starter would when it draws a couple hundred amps.

There are several different configurations for the clamps that go on the battery posts to convert them to wing nut connections.

Is this possibly what you are questioning?

No...I'm asking what the little box is that is connected between the posts.

Lawrence,

I'm interpreting your diagram that the '-' and '+' are your battery posts (the drawing of the actual battery is left to the imagination) and the little box is the thing-a-ma-bob in question. A fuse of some type?

Unfortunately you may find it difficult to get a solid answer without a photograph as floyd is patiently suggesting.

Lawrence, I'm thinking the little box is a circuit breaker to protect your battery in case there's a short somewhere. It will break the circuit when it gets hot but then connect again when it cools down. You might find an amp rating on it. It's sounds like the guy who installed your battery did you a favor.

Here's a link to some automotive circuit breakers:

That is a strange wiring diagram..... I have something like that just outside my battery box but it is a "Automatic Resettable Fuse" except that it's wired inline on the black positive cable just before the battery box. That fuse protects the whole system from the battery.

I would guess that the party who installed the battery did not know there was an inline fuse as its often hidden under the rat fur inside the trailer in the front bunk area so he decided to give you something better. You probable will find you also have an inline fuse as Joe has.

It's a Circuit Breaker that looks to be installed incorrectly.

Thanks for identifying that item...could you be more specific about the incorrect installation? The connections are (positive): to battery positive, and from the circuit breaker to the trailer fuse (I also have power to the breakaway switch wired to this post); (negative) to frame ground and to trailer ground wire. I think Carol and you were right about the installer weren't aware of the trailer fuse.
