Not sure what is wrong but after the gimbal failed to initialize, I opened up my phantom, checked all wiring, connections, etc., and everything there seems correct. The gimbal appears to be getting power and I am hearing some noise coming from the motors but it is not doing what it is supposed to do.
I know I have a low post count here and some might think I don't know what I am doing here but I have had considerable past experience in working with electronic gear and started off my career doing digital circuit pack repair and troubleshooting for AT&T for a couple of years. Before working on my phantom Iast night I also replaced the power supply filter caps in an old Cerwin Vega subwoofer I have that had developed a nasty buzz, if that gives some idea of my experience level with electronics.
One thing I am noticing is that the GCU appears to have a small LED next to the port where the gimbal cable is plugged in, but it does not light up when the battery is connected. Is it supposed to? In any case, I think I am going to have
to send mine back, will be calling Dronefly later this morning.
Well for what it's worth, I found my problem and fixed it, and there was nothing wrong with the gimbal. I contacted my dealer for support and they suggested upgrading to 3.14. When I did that I discovered that I had an IMU initialization failure due to the z axis on the accelerometer being stuck. Keep in mind that I had not actually attempted to fly and was just checking out the gimbal and I didn't really look at the LED codes and I just presumed that when it didn't work right off the bat, it was a wiring or connection issue. But last time I'd flown I had a minor crash into some hedges and I guess that was enough to put the IMU out of whack. I did the old trick of removing the NAZA and banging on my desk and it is working again, and the gimbal is now working. Now I just have to put everything back together.
