I have an SRC. The fuse is right near where the battery goes, if your model is the same as mine. I have the original SR4 carbine, with the telescopic stock.
Consider the motor, too. Before it stopped entirely, did it make any noises when you tried to fire it? My SRC has died on me for the past four games straight...after being fixed each time, as well. First time was a gear (which was replaced with CA), and the other times has all been motor sh*t.
