We taxied out on a clearance to use Charlie and Alpha to 17L. As we approached the Charlie to Alpha Y we saw a sign near where the H is on the chart to the left of the Y. It said to go the left to join Alpha to 17L. As I stated to the Ground controller told us to turn right and continue on Charlie to the right and then join Alpha. I immediately complied and we stayed on the hard surface.My FO and I agreed that we had both been snowed by the sign which had indicated to turn left towards Kilo instead of continuing on Charlie to Alpha. Bad signage was at the heart of the problem. Afterwards we taxied uneventfully to 17L.I hope that other unsuspecting pilots that have been caught in the same trap will cause SCEL ground ops to replace the signs leading to Alpha and Kilo. Review of the signage used by SCEL Ground Ops with a clearer depiction of taxiway A's origin northbound.
B777 Captain reported they had difficulty with taxiway signage at SCEL airport.
