Flight Crew Rejected Takeoff; Flight Crew Returned To Gate; General Maintenance Action
Aircraft
Cleared for takeoff and approximately 10 kts we had a 'stall fail caution msg' which triggered a low speed rejected takeoff. We exited the runway; performed the required checklist and called Maintenance. As I was explaining the situation to Maintenance we also discovered the APU Batt CB had popped and the yaw damp status msg was being displayed. At this point Maintenance decided we should return to gate and ground the aircraft. All appropriate communication was established and no further incidents arose. The flight was eventually canceled.
CRJ-700 Captain reported a rejected takeoff due to a stall fail caution message and popped APU CB resulting in a return to gate.
