Have you checked your toad breakaway lately?
I recently tested my toad auxiliary braking system, a Blue Ox Patriot, in our toad. After setting it up I activated it with the wireless remote controller, then returned it to its normal position. Then I pulled the plunger out of the breakaway switch to test the breakaway. To my dismay, nothing happened. After a little troubleshooting, I decided the breakaway switch was bad.
I ordered and installed a new breakaway switch and the system works correctly. I tested it by operating it normally with an external battery, feeding through the motorhome cable, to be sure everything worked. Then I disconnected the external battery and pulled the breakaway switch plunger, causing it to activate with its internal battery, which is the way it is designed to operate.
So, when was the last time you checked your breakaway?
