motors will spark when they turn.

this gun came with a factory mosfet? If all you did was plug in the battery and it started shooting, the mosfet is fried. Safeties in these guns are a mechanical block to prevent the physical trigger wiring from closing the circuit.

If you plugged the battery in and it ran away with the trigger not closed, the solid state switch in the fet unit has failed and it's shorting there.

Provided you don't have a cut wire making the short on the trigger path.

Not that I think would matter a whole lot, but what size battery do you use? There's a number of things that can contribute to a fet frying, and most of the oem fets that come in guns are pretty low quality that can't take massive current/voltage spikes by themselves. A number of hand built designs out there for 20 bucks are much more reliable in dealing with spiking that occurs in airsoft guns.
