2014 Focus only starts when jumped
My girlfriend left her focus sit for a few months and now it only starts when
jumped. Yesterday we drove it around for half an hour and then let it idle in
the drive way for another 15 minutes, as soon as I turned it off it failed to
come back on. It makes no noises, or sounds of any kind, and none of the
electronics work at all. No dome lights when the door opens, no dash gauges,
nothing. I thought the issue might be because we weren't letting it run so the
alternator wasn't able to charge the battery, but after 45 minutes of work
yesterday I don't think that is the issue.
The battery terminals look good and clean, I haven't looked inside the cable
coverings though. I'm very unfamiliar with this car so I'm not sure what other
issues to look for.
My guess is the battery is weak and needs replacing based on repeated jump starts. They only last 3-6 years on average. Is the battery original to the car? The alternator can only charge it so much and the older a battery gets, the harder it is to keep a full charge. You can test it yourself or have an auto parts store do it for you. You should have over 12 Volts engine off, 14V engine on if the alternator is working properly. But if it wasn't you would have a battery light lit up on the dash.
Thanks, I'll get her to take it in and get it tested. There isn't a battery light coming up on the dash, but last night when we jumped it, the check engine light came on. She told me the battery is the original
