moomba boatmate trailer brake lock-up
Please help ! For some reason (I think maybe the kids yanked the break-away brake cable) I cannot figure out how to reset the trailer brakes on my Boatmate swing-away tongue trailer. I can go forward, but I am locked up in reverse. Has this happened to you? Kinda hard to get my Mobius LS in the water driving in truck first

There are two things you can do. There is a metal filler that came with the trailer which fits in the track that the actuator slides. So pull the trailer forward so that the pin of the actuator is in the forward part of the groove insert the filler piece which will need to be held in place by someone while you back up. This piece will not let the brake actuator engage.
The other thing you can try is take the electrical 5 pin from the trailer put the last pin (furthist from the ground) in the second pin of the vehicles harness and turn on your lights.
The last pin on you trailer harness de activates the disc brakes.
I have had this problem , if I tow with my truck everything is fine but if I tow with my Saturn outlook the brakes won't let you back up.
I hop this helps

I think if the kids had yanked the cable you wouldn't be able to go foward eather. If you don't have the metal circle that goes in the hole in the side of the tounge to keep the brakes from actuating a nickel and some duct tape works.

thank you
Thanks for your suggestion ... you saved the day today for wakeboarding. I stuck in a nut the size of nickel and duck taped it in (I never travel anywhere without a roll of duck tape). I'm very mad at my dealer; I bought the boat new and the dealer never mentioned this feature, nor did he give me the very high teck lock out mechanism when he did my walk through. I will go pick up a 7 to 5 pin adapter today. Obviously my 7 to 4 pin adapter I tried to use does not work. Thanks again guys.

windmere,
The towing vehicle's back up lights activate a solenoid in the trailers mastercylinder to bypass the system when you are going backwards in reverse. This is a mechanical surge brake, when you hit the brakes on your tow vehicle the mass of the trailer pushes forward on the coupling causing the brakes to apply. The beauty of the system is they are self balancing. At first the trailer is going faster than the tow vehicle causing it pushes on it's own mastercylinder until the speed is balanced between the two. Now when you are in reverse you are pushing on the brakes hence a need to de-activate them and the back up light are used for this purpose as they are only used while in reverse. Your use of ducktape was great I would not suggest that ANYONE stand behind the vehicle while backing up to hold the anything in there to deactivate the brakes.

Yep, the second pin trick works is someone has taken your five pin and left you with a four - move the whole thing over two - worked for me.
Kipp, are you a pilot?
