i have a ford focus that the entire electrical system has failed

Asked by Jul 19, 2016 at 03:34 PM about the 2009 Ford Focus SE

Question type: Maintenance & Repair

I disconnected the battery,observed it charging,walked away to let it charge. I
returned only to find that the battery cables returned to their rest position near
the terminals and shorted out on the charger clamps. Now the car has no
power available at all. I checked the fuses in the engine compartment that
would release from the block some will not release and gave up trying to
access the fuses in the passenger compartment, they are quite difficult to
access. Can someone narrow  down the possibilities to a solution to this
problem?

Burned out a fusible link would be my guess. In the future when you remve the battery cables from the terminal cover the terminals with something, like an old spraycan cap. That will prevent the cables from flopping back into place and doing just what they did to you.

Please tell me that you did not disconnect the battery cables with the engine running, this causes a power surge that can fry the vehicles electronics. That being said, a blown fuse link or main fuse is the most likely problem, use a test light to check for power through each one of them if you see it physically blown. Once you do find it the security system will be activated so make sure you read on how to shut it down in the owners manual before attempting a start up. There may also be a problem with the BCM after you get it started, some vehicles in your year will loose all memory of the presets if battery power is lost, so if you have problems with some of the accessories like windows, radio, etc, then a trip to the dealer is in your future for a system reflash.
