Hello - I am fairly new to this and after about 15 trips in my little RV I realized I wasn't hooking up the breakaway cable as it was broken and zip tied through my safety chains. I've ordered a new cable. My RV has a switch installed and through all my research I learned that I need to check the battery. I cannot find a battery - I crawled underneath and looked all over. Does the breakaway switch have to have it's own battery or is it possible to run off my 12V? Thanks in advance for your help. I have a 17 ft ECO by Skamper travel trailer. I tow with a Sequoia and have a brake controller installed in my TV.
It does run off your 12V. But your TT has to have a battery to run the 12V when not hooked to your TV. It WILL work off the TV power, UNTILL it unplugs it self. then the TT battery takers over. If no battery on the TT. No breakaway brakes once it pulls out
