Help please
 

Hi,
While setting up a model with 12-22RIIIGyro I disconnected the battery went away for a minute ,came back and plugged the battery in,but.. there is absolutely no response ,I changed to another battry, same result...I switched to the other battery inlet again no answer.

Is there some kind of 'fuse' or something in there ,am I just doing something stupid?


Thanx in advance...
