Narrative:

Aircraft arrived at gate with logbook write-up of electric smell during taxi in to gate before APU start and all system appear normal. Aircraft was ventilated and checked all compartments from avionics, cabin, cockpit baggage, etc. Could not determine what the source was. Ran bite checks of electronic system, avionics cooling, air conditioning, blowers, etc. Coordinated with technical center -- could not duplicate and all checked ok. There were no faults or failures on postflt report. Did not find a procedure in manuals for this problem since all checked out with no faults. Aircraft was released with no incident for several days. The reason for filing this report is that at the time I feel everything was done and checked properly to dispatch the aircraft safely.
