Test the breakaway switch:
1. Hitch up and move the trailer a few feet
2. yank the lanyard to pull the pin
3. try and move the rig.
If #3 requires way more pressure on the gas pedal than usual, everything is OK. Put the pin back in the switch and drive off. Confident that if you have 2 failures (drop off the ball AND the chains break) the trailer will stop.
If you can
move the rig the same as always, something is not doing it's job! Get it fixed as soon as possible.
If you can't do #2 (that didn't come out right) then replace the switch and re-test.
