2, 4 Cell AA Battery Holder Case with Servo tester can be widely used to test the RC digital servos which is with JR plug as well, such as for model 9g micro servo, tiny 1.5g linear servo, FS90R servo, DS3225 digital servo, DS3218 digital servo etc.
3, The red wire of the holder is to connect with "+" of "IN" of the servo tester, and black wire is to connect with "-" of "IN". The other side which marked "OUT" is to connect with servo, normally red wire is with "+", black or brown wire is with "-", and the rest wire is with "signal".
