gee
what kind of plane was it?
when you were on the ground, did you re set the breaker, turn the pitot heat on and touch the pitot to see if it heated?
things get broken, a short circuit or something else. get a mechanic ( I think you call them engineers, but that is what we call locomotive drivers and science types).
and have the mechanic fix it.
be glad you didn't have a fire, the short could be ssomewhere bad
