Narrative:
Picked up aircraft X out of maintenance written up by another crew for various items; but none related to avionics. When preflighting the aircraft; in cockpit on circuit breaker panel behind co-pilots seat; found the avionics master feeders PS1 circuit breaker popped and on the avionics master bypass switches; found the PS1 and PS2 switches selected on. These are items normally not used by pilots. I am concerned this situation may have be done when a 3rd party vendor located out of ZZZ1did when working the airplane and didn't reset the condition they were doing. Either way; with no history on the airplane; we wrote it up for maintenance to troubleshoot.
