Has anyone wired a trailer brake control on a 700 EFI? I haul a lot of firewood and water, too much some times, and it would be nice to have some trailer brakes. A lot of up and down hills hauling sap for maple syrup. I'm getting ready to build a new trailer, and the axle I'm going to use already has brakes on it, if the quad has enough electric power to run them, I think I'll give it a try. Anybody have any ideas?

 

You could check and see what the amp draw on the brakes are then tap into the brake light wiring and check what your output is. You would have to add a trailer brake controller as needed in a vehicle.

Get R Done then show us the results.

 

You could mount an automotive battery on the trailer, and run a charging wire from the atv through a plug-in connecter at the ball mount area.

 

I think the electric brakes would be fine. Seen someone making a atv trailer with them. Most trailer parts suppliers would be able to tell you the amp draw, or you could check it with a amp meter.
If your bike brakes/ebs can sort of handle the load now, you won't likely have your trailer brakes on too many mins out of an hour. Therefore your battery should have time to recover in between. If not then you could add a second battery.
The emergency brake battery on most ta trailers (4 brakes) is about the size of a atv.
I would not just wire it to you brake lite on the bike though, probly overload the switch. Just wire a spdt relay in there instead ($5 part, from napa etc)
Activate it from your brake lite, but draw the current straight from the battery. Or better yet add a trailer brake controler.
Don't forget a ground wire back from the trailer to the bike.

I seriously considered it on my trailers , (see photo page, I used 2000lb high speed axels), but come to the conclusion any hill I can climb without "running it" can be slowed to a controlled speed on the way down. (you do have a 4 stroke engine, preferably with ebs) But I would not say I could easily stop with the est 2000# load. And I don't tow that heavy in hills vary often. But brakes would not be a bad idea.

you could run the wire from the accesory wire port id imagine...

 

I was thinking the same thing. Get a deep-cycle marine battery that's meant to charge and discharge. I got one a few months ago at NAPA, around 5o-60 bucks it was. I use it in the summer for a bilge on the boat, and in the winter I clip it to the quad to run the headlights when the quad's off (to light up the ice rink).

Charge it every few days/weeks as needed with an automotive charger, or put a trickle charger on it every night.
