My wife's 2011 XC70 (3.2) was parked by her last night - working fine. This morning she tries to start it and it doesn't turn over. I took the battery out today, had it tested, also put it on a charge for a few hours - no issues with the battery. I put it back in the car and tried to start, normal dash lights come on, it makes the normal initial sound but doesn't turn over at all.

What else should I be checking on it?

Thanks in advance.
