Wiring Breakaway Switch

[cole3444]

I currently have a 72 Sovereign that I am trying to hook up the brake wire and the breakaway switch. Have a #10 coming from the brakes and one from where the breakaway is mounted, both are grounded. Been five years since I did this on my other Airstream and want to know if the red wire from brake terminal connects to the 30 amp auto reset breaker stud that comes from the + side of the battery and the other wire from breakaway connects to the other stud. If not can someone help this old feller get his brakes working. Diagram would be great so I will have it for future issues if needed.

I can't help much but maybe a little. The 76 Sovereign I worked on this winter is gone along with its service manual. I can try to copy the brake circuit out of my 75 Overlander manual once I get the trailer back in the shop.

We just installed new axles on the Sovereign. We wanted to test the brake wires before connecting them. On the first test for the presence of 12v at the brake magnet wire was a no pass. I found a loose ground in the 7 pin connection box in the front of the trailer. Fixed that and all was good.

The brake magnets are proportionally energized by the tow vehicle driver's foot pressure on the pedal, or a full 12v to the magnets the brake away switch if pulled. The Sovereign brake away switch was powered by the same wire as the tongue jack. But I did not trace or understand where the brake away wire was tied into the trailer brake wire to the magnets.

I bet someone will chime in with more information than I have provided.

Thanks for the response, like you I figured others would chime in on how to connect the brake wiring. I hate it when you forget how you did something but that's the way it goes. Thanks again
