Question about 2004 Ford Focus

1 Answer

On two occasions in the last 3 days on starting my car (Ford Focus 2004) the electrical system has gone into 'spasm' headlights, radio & dash indication alternating on/off . On switching off engine and restarting problem corrects though on second occasion battery charge warning light stayed on for a short run period . Is this simply battery or more serious? Thanks for any assistants Dave

My abs light on my 2004 ford focus has been on for 10 days now, before it would come on here and there but would go out usually after i shut off the car and put it back on now it comes on as soon as i

All your saying is you have no idea of the technology
that has been on all cars for the last 32 years

You know nothing about O BD Vehicle Systems that most people
do & no idea what to do when you start a car & any dash light stays
on or flashes

It pays to use the internet to learn those things & read an owners manual,any owners manual,doesn't have to be for your car

You check for codes or have a repair shop do so then diagnose the
system with a fault

It seem odd to me that you would use a car with any light on & only
go to the internet verse a repair shop are you not concerned about
what the issue might be

Got a focus 1.8 deisel zetec 2006, had an engine systems fault light on for past few days, lack of power at speeds up to about 50 mph then seems to clear and call pulls away and light goes off, maybe fuel...

If no lights on dash then the battery terminals are corroded high resistance, if you have light in the dash and still the eng doesnot turn then I would suspect the starter selonide. As for the system light you migh have to get it scanned look into History codes.

Sounds like you have something pulling the battery down. Is the radio still factory? If not my first suspect is an after market radio. If all is still factory, no radio, no alarm system, no back seat chargers, dvd players. Your alternator may be the cause, alternators have diodes that can cause a "leak" or a small draw on the battery. If you have a volt/amp meter you may be able find this. If not take the car to auto parts store where they can remove the positive cable and read the amp pull, in between the battery post and the cable end. You will have a very small amount due to the radio clock. but if your reading is in the 1 - 3 amps that is too much and causing the batt. to go dead after 3 days. Disconnect the largest wire on the alt. and read the amps again, if it has gone down and reads normal, that is the alternator diodes leaking, and shes bad. Hope this fixya up.
