I accidentally pulled the pin on my emergency brake away control.  Re-inserted pin, trailer will haul fine.  But I now have no brakes on trailer.  All my lights work, so it is not in the plug.  Just not getting any "signal" to my trailer brakes to engage.  I feel it has something to do with the brake away control as my brakes worked fine until this pin got pulled.  I have hooked to 3 different trucks, all with same results.  This is a 1997 Featherlite 4horse GN with weekender package.  I am at a loss as to what to do next.  Is there a fuse somewhere that I am not finding to reset?  Checked trucks, all fuses are good.  Don't see any fuses on the battery to the break away brake box either.  What's next?   

Is it possible the break away battery was installed incorrectly? If so you probably burnt up the brake controller in the truck. Did you smell anything electrically burnt or hot in the truck cab? Try hooking the trailer up to a different truck and see if you have any trailer brakes.

Hope this helps, Paul

If your truck will not activate the brakes on three different trailers, the problem is most likely with the truck and not the trailer (s).

If you have a 7 pin RV type of truck plug, find the blue wire that is at the  5 o clock position. With a multi meter, put the red lead into that terminal. With the black lead, insert it into the terminal at the 7 o clock position. Apply your truck's brakes and check for about 13 volts.

If there is no indicated voltage, your controller is either inop or not receiving its voltage from the truck. If there is a lighted indicator light on the unit, it may suggest that it's receiving the voltage, but has an internal problem, and is not sending a sufficient supply to the brakes.

The B plus wire going to the controller, should be aprox 13.5 volts or more. If there is power to the controller and no power out, the controlller is bad. If there is no voltage to the controller, the truck's supply fuse is blown, and the controller won't work.

Probably something to do with the break away plug.... When the plug is pulled, the brakes are applied by the battery, which probably disconnects the blue wire from the truck, keeping the current from feeding back to the truck. When you plug the break away back into it's slot, something is not resetting and letting the truck brake current flow to the brakes themselves. The current flow to the brake battery is charge current, not trailer brake current.

I read it wrong, thinking you've tried three different trailers, not three different trucks.

I agree with the others, when the switch was pulled, a wiring problem developed, and perhaps the switch did not completely reset. It's a very simple electrical system on the trailer side, starting at the battery with its switch. In the wiring of our trailers, the red wire from the battery then goes directly to the brakes.

At the most, a new break away switch can be installed and a new power wire run to feed the brake assemblies. Parts wise, fairly inexpensive, labour wise an hour or so.
