Question about 2004 Ford Focus

1 Answer

Wipers slow down, radio crackle, battery light comes on, then no power at next startup, the battery is flat . After a full re-charge to battery, alternator is 'fine' and so is battery but problem has happened before, about a year ago. On checking alternator, it puts out first 12 then 14 then 14.5 volts. Mechanic says change alternator. Can it be the radio connection sending a 'dirty' charge? Over the years, the engine has been 'jerking' now and then, at various speeds.

When not running the engine for a week, the battery dies. When I jump start it, engine will start cranking very slow and pickup speed before it starts running.


it seems like the battery is going. clean battery terminals, also the grounding to the body (engine block, transmission, etc.) all should be shiny cleaned. suggest you go to autozone (or other auto parts) for a free battery & alternator tests.

Was the battery checked, if not check if for any dead cells., and make sure its taking a charge. A bad or weak belt tensioner may be causing the problem.

Charge the battery start the engine and confirm that the voltage at the battery is about 14 volts with engine running . If not it is likely the alternator is bad or the electrical connections from the alternator to the battery are defective.

A significant drain from the battery can be determined by observing the battery voltage after stopping the engine.

If it is under 12 and continues to drop trouble shoot for battery drain. If you suspect the radio pull the fuse and observe.

Battery light, ABS light, and Oil light flashes on and off when driving the car. Dash lights,front marker lights, and tail lights will not come on until the car is warmed up.


Electrical problems are hard to fix. You need a voltage test for the charging system and a battery test.

The oil light, abs light, are not hooked up to the turn signals. Never heard of balance of lights coming on in that manner.

The heater fan, headlights, and wipers will slow if the charging system can not keep up. Battery light is accurate to show discharge.

Trans shifts can be affected by voltage. Some transmissions use electric solenoids to shift and they mix voltage to get different gears.

2005 mercedez benz 350 slk radio will not come on


Hi Gennea, If the battery runs flat and the radio looses its anti theft code it must be input again before the set can work. The code may be written into the user manual, if not you may have to visit an agent. Regards John

Have the alternator tested. Sounds like either the charging system has a problem or the belt came off.

While driving the car turned off and will not start. Just prior to that the wiper was slowing down like it might stop working. When trying to start it the is some click click sounds. Any idea what is...


It's possible your alternator has failed. Remove the alternator and have it tested at your local parts chain. Please let me know if you need instructions or have any other questions.
