Departed and cleared to 2;000 expecting 7;000; I got distracted when my gyro CB popped with a strong smell of electrical wiring and flew through 2;000 to 3;000 and when Departure saw my error; he told me to maintain 3;000. I am too dependent on my autopilot/Flight Director (FD) and when it all failed; I got distracted; again!
PA-23-250 pilot reported he climbed through his ATC assigned altitude when his gyro CB popped.
