I'm stumped.
I'm trying to make a connection with a non-EZ GWS servo but am having no luck. I've tested the EZ with standard servos that came with the kit and they function fine. This GWS is rated at 4.5 volts to 6 volts and I've tested it at these and even lower. The port is correct, the board is properly selected, I restarted the EZ, insured I have the latest version but still get no movement or indication a signal is reaching the servo. It doesn't appear locked because I can turn the gears by hand. I'm hesitant to take it apart just yet.
Any suggestions?
Thanks,
Daniel
I see that you marked this thread as resolved before testing which it clearly looks like it is not. If you're still having trouble with this make of servo with a NiMH battery and the wiring is correct, then you should really consider change to another make of servo as I suggested before.

I closed the thread because I think the question was resolved. I tested the servo with a 6 v NIMH battery (fully charged) and its pretty clear the servo itself is dead. When I connect it to the EZ the board shuts down (blue light goes out and the connection is broken) and it happens with each of my 3 EZs. All other servos work fine, unfortunately I need a heavy duty one to lift this head. I'll look around at other brands. Again most likely the damage happened with me testing it and I fried something inside. I've tossed into my bin of "damaged but possibly salvagable goods"
Lesson learned.

Can you consider using a larger scale servo like a Hitec HS-805BB... ?
That servo may work if he adds a servo helper to it like springs. It's certainly a decent price at $40 USD. The bubble section he's trying to lift can weigh more then 5 lbs sometimes. The HS-805BB is a plastic gear servo. This servo also comes in a metal gear model (HS-805MG & is $60 USD). That one may stand up to the pressure better.
Another option would be a standard servo using a ServoCity gearbox. You can get them that will handle up and over 200 Oz-lbs with different mounting options. A bit pricey at $240 USD but it will lift a horse and is very smooth. To lower the price you could order it without the high priced HS-7950TH servo and install a less expensive standard size servo.
