It's not my car, it's my fathers. It's a 2003 Accord V6 coupe (auto). He took it to work this morning and got there fine. After getting out of work he then went to start it up, nothing. So he had it jumped by a fellow employee and drove it back home..about 5 miles. So then he got it home and we tried to start it again, and got nothing. So I took my car and tried to jump him, this time the car wouldn't even take the jump. When you turn the key there is just a lot of clicking and doesn't turn over. I'ts not the battery because that was replaced in March, so it's fairly new. I was thinking the alternator? Any ideas has to what the problem is? Thanks in advance.
