Narrative:

I was driving (taxi) an aircraft to do an engine high power run (trim). The tower gave me directions. I proceeded to taxi (in a big downpour of rain). When I reached the taxiway where I was to turn and when I reached my turn it was unclr to me which way to proceed. Then realizing I passed my taxiway to turn, so I stopped immediately, called the tower and was given a new route, so I continued.
