G&G ETU/Mosfet issue

[Harryking]

So I reshimmed my gearbox and re-greased my gears etc and put my gearbox  back together and installed a new motor. As soon as I plugged my 11.1 Lipo in it blew the fuse without  even pulling the trigger. I then removed the motor from the gearbox to rule out any gearbox issue. Put a higher amp fuse in and plugged the battery in and immediately the motor started to spin (without touching the trigger) and the connection between battery and gun started to spark so obviously disconnected it. Any help much appreciated. Thanks guys

Sounds like you may have pinched a wire and caused a short. It's going to be a case of carefully checking each section of wiring with a multimeter to track down where, unless the damage to insulation is obvious.
