I have a 1999 Honda Civic Si and recently put in a new battery. Just a few days after installing the battery I am having trouble getting my car to turn over. All it does is make a single loud click and nothing happens. I know it isnt the battery because i have full power to the car headlights, radio, etc. Also the Altenator is fairly new, just about 3 years old. Any suggestions as to if i need to get a whole new starter or just replace the starter relay?
