Narrative:

While repositioning aircraft, the crew was issued the clearance 'taxi via taxiway west to taxiway J....' while taxiing, the crew made a wrong turn and nearly crossed runway 5R/23L (active). Crew interaction along with ATC direction to stop and turn around averted a potential runway incursion. Contributing factors: 1) poor taxiway markings and layout. 2) poor airport diagram depiction of txwys at that area. 3) inadequate review of airport diagram. 4) low light (night). 5) inadequate taxi light. The failure of the crew to follow ATC instructions was caused by unclr taxi instructions and inadequate review of appropriate airport diagram to familiarize the confusing taxiway intersection. Callback conversation with reporter revealed the following information: reporter said that the area is wide open with only taxi lines defining the txwys. He was using the commercial chart but admitted to an inadequate review.
