Narrative:

At 22000 ft during climb out the gust lock caution light illuminated. Followed by a strong electrical burning smell. We completed the appropriate checklists. Declared an emergency and returned to ZZZ with no further incident. Supplemental information from acn 620642: noted gust lock circuit breaker popped and burning electrical smell. Callback conversation with reporter acn 620496 revealed the following information: the reporter stated the burning smell was found to be a solenoid in the gust lock circuit located in the pedestal that was overheated. The reporter said the solenoid performed some sequence function in the ground throttle lock. The reporter stated the burning odor was strong. Callback conversation with reporter acn 620642 revealed the following information: the reporter stated the cause of the burning odor and illumination of the gust lock warning light was not reported by maintenance to the flight crew. The reporter said the gust lock circuit breaker was found tripped. The reporter stated the aircraft operations manual has a procedure to follow for light illumination.
