Hello Bill!
do you remember trying placing reverce polarity conection with your bateries to your powerbox?
multiplex conectors have mold shape to avoid that but with litle extra force you can do it..
powerbox thinks somethink whend whrong and stay open so you can land.
bottom end there is nothink you can do.send it back in for service
good luck
reverse? battery? that would be smoke
he says he has power on both packs he just cant shut one channel off.
best guess is that your switch is faulty.
try to connect the batt one to the batt 2 input and see if the problem reverses.
or have a look at the connector on the royal (switch input) and see if one of the small pins is bend or missing.
