Strange problem - one servo works but two (Y-connected) don't?
Have a very weird problem at the moment, I have my ArduPilot (328 board) aileron servo output to a Y-lead for a servo in each wing half, however just suddenly the servos appear dead but when I plug the servo's in singly they work.
The Y-lead is fine as when the Y-lead and two servo's are plugged into the elevator output everything is fine, the plug and pins are fine, continuity is fine & checked for dry joints. 'Radio_Test' serial outputs show the radio input fine too. It's almost as if there isn't enough power but strangely just on the aileron output?
Any ideas on what's going on?

Thanks, I seem to have solved it, I went over each leg of the chip that controls the servos with a fine soldering iron, a little solder and flux and that seems to have sorted it out, will just do some more testing now
