What is this?

I had a weak battery that I replaced this weekend. Beside the battery enclosures were these two coils. They look like electromagnets. Any idea what they are of what they are for?

Looks like electric brake magnets

Thank you,

Google search, found a picture that matches Brake Magnet, Kelsey Hayes Round Type. They were wired into the break controller yet were laying beside the batteries rusting.

Buying a preowned rig saved $ but causes some mysteries!

Apparently the previous owner had a couple spare brake magnets.

Just a cheap way to trick the truck brake controller for electric over hydraulic brakes.

Howard, does the RW have Disc Brakes?? If so, I agree, previous owner's way to make the Hydraulic pump work with their TV. Correct way is to install a CAM Interface module in the brake controller line before the Pump.

I ordered my new 31SL (due here in two weeks) with Disc Brakes. Are you telling me that I will need to purchase and install a CAM Interface module for my new trailer?

No, it will already have one. I think M&A was asking because someone may have modified theirs or even added disk after purchase.

I really knew very little about this rig from the description posted on the internet. It said microwave, yet from the pictures it looked like the microwave/convection I hoped for. Didn't mention heat pump yet it's got it. I think it's got most options except the second awning.

First trailer I've had with disk brakes.
