TM M733 not firing.

[RobFromWinnipeg]

I just pulled out my m733 that ive had sitting unused for i would say over 7 months. Now for the life of me can't remember when i used it last but i charged the battery, plugged it in, went to fire and all i heard was a high pitched zzzzzzz, zzzzzzz, ,zzzzzz, everytime i pulled the trigger in semi, and a continuous zzzzzzzzzzzzzzzzzz on full. I think the last time i was plinking with it the battery died on me during fire cycle, and my dum ass just left it and forgot about it. I have never taken apart an aeg myself but have seen it done in front of me a few times. I just would like to know the first things i should look at. The gun is not cycling back the piston and theres no movement apart from the motor as far as i can tell. When i did pull the trigger it didn't sound like and think broke/stripped. just a high pitch zzzzz sound ( as best as i can describe). It feels like some gears may be turning as is doesnt sound like the motor is locked up.

Now I know that chances are i won't be able to do this myself without doing more damage to it, but i was wondering if any of you have had a similar mishap and would know what most likely failed.

Thanks .

Is your AEG upgraded?
When you store the gun away did you decompress the spring/piston?

You may have stripped one of the 3 gears. or your piston teeth have stripped.
Look inside the bb chamber and see if the nozzle moves back and forth as the motor turn. If it does then your gears are fine and that your Piston teeth stripped.
