Now you've got me worried... you should be able to easily lock the trailer brakes on a dirt road with any controller, especially with the manual control.
I guess I'd be pulling the brakes apart again and checking the magnets, lever arm, shoes and drum faces.
I don't wanna sound condescending, but wanna cover all the bases.
Are you SURE the brakes are adjusted properly?
Did you clean everything well with Bra-Kleen before reassembly?
Were the magnets dead flat against the drum? Were both those surfaces in good condition? It isn't the magnet on the drum that stops the trailer, it's the drum pulling the magnet on the end of the lever that cams the linings out to the drum which stops the trailer. If the magnetism isn't strong enough, or if there isn't sufficient grip here, the drum can't pull the lever arm hard enough.
Are you sure the correct arms are installed correctly on each side of the trailer? (if not, it's easier to lock the wheels backing up than it is going forward).
With the high amperage, I'd be tempted to skip checking wiring, but wouldn't skip it. I'd check the voltage and amperage to each brake and really look over the trailer and truck wiring carefully.
Hope this helps,
