Hello everybody. Here's Frank from the North of Italy. Labrador trainer.
First of all congratulations for the fantastic forum.
I'm trying to repair an old 8 shoot Bumper Boy. That's not my first repair but I don't know what to do at this point.
The transmitter works fine and when I press the Launch button the receiver's red led blinks but nothing happens (but the servo make a very low noise, like as the electronic can't power them correctly).
I tested the servo motors and they work fine when disassembled and tested with a 6v battery.
the PCB looks fine, nothing strange. The only thing I can notice on the board is a missing jumper on JP1 (but I don't remember if in my other BB this jumper was present).
Has something similar happened to someone? please help!
Thanks in advice!
Frank
