Trying to help elderly neighbor; said her 2014 Fusion would not start. I turned key; no result. No headlights, but parking lights would come on. Battery read about 9.5 volts on analog meter. Jump started car and read about 13 volts on analog meter.; no change when engine was revved. She took it to a brand name parts store for testing. They said battery was shot but they could not change it due to its location up against firewall. ??
An hour later, she went to local Ford dealer. They claim battery is fine, all systems ok.
Anyone have any thoughts? Many thanks.
