The fuse should be in the same fuse block for all the other chassis circuits like turn signals, horn, wipers and so forth. Look on the front of the fire wall over engine. You should also look under the dash if need be. Make sure the belt did not break if it has its own belt the rest of the engine components will still be working and you not have an engine or charging issue. Good luck and keep us posted.
