[AT] Trailer brakes

[Paul Waugh]

I test my trailer brakes by hooking up to truck, put a small battery charger 
straight onto trailer terminal s (positive & negative) at trailer plug. You 
should hear the brakes, clang/pop/grab. Then I pull the trailer ahead a 
foot, if wheel lock, brakes are working. Just my 2 cents, at least I know if 
it is truck or trailer.
If wheel don't lock, I move charger back to wires coming out of axle and 
repeat.
