Just a footnote here re: Breaks and breakaway switches.
If you have any type of trailer in B.C. with electric brakes
you must have a fully charged wet cell battery
installed in the trailer with a break-a-way switch that has a cable attached to the tow vehicle so that if the trailer tounge snaps off or comes off the ball it will pull the plunger out of the break-a-way switch and lock the brakes
up for a minimium. of 15 mins.
That is the Code, no exceptions. Drycell batteries are not legal!
I really got run through the hoops years ago over this when we bought our first horse trailer.
The law is different in Alberta where we bought our Feather light
horse trailer and had to revamp it when we got back to B.C.
Having said all that, I know for a fact that there are lots of trailers on the road here that are not setup the legal way.
