Narrative:

I was cleared to taxi to runway 24 for departure from the FBO via twy P to twy left and then to hold short of runway 19. Prior to reaching runway 19 I was cleared to cross runway 19 at twy left. Upon reaching twy B I turned right on twy B and then realized that I had turned on the wrong taxiway. I found the signage at that point to be unclear; and I suspect this problem had occurred before; because the ground controller told me to taxi across 19 at its threshold. That was difficult to determine. In any event; prior to entering runway 19 I realized my error; and queried the controller; who then told me to turn left on runway 19 and then right on twy a. I then completed my run up and received my IFR release.

Narrative: I was cleared to taxi to RWY 24 for departure from the FBO via TWY P to TWY L and then to hold short of RWY 19. Prior to reaching RWY 19 I was cleared to cross RWY 19 at TWY L. Upon reaching TWY B I turned right on TWY B and then realized that I had turned on the wrong taxiway. I found the signage at that point to be unclear; and I suspect this problem had occurred before; because the ground controller told me to taxi across 19 at its threshold.
