Hi Folks
Getting a whistle/buzzing noise coming from engine while driving. Lights clicking inside the car (Defrost, abs, and radio goes on and off, etc...). Arrived at home and car won't start back, batterie is dead.
Though about the alternator and changed it (Ouf !) but still the same ?!?!? Let the car run for 30 mins but the batterie still dead.
So is it the battery ?
Do you think I chnaged the alternator for nothing ?
Thank you very much !!!!
The intermittent lights, radio, etc sounds more like a bad connection or other wiring problem. Still, would be worth ruling out the battery, especially if it is original to 2006 or 7. The battery will show less than 11V if it has a shorted cell; though doubt that is the problem as most cars won't even jump start when this happens. Corrosion on the terminals or internal to the battery can cause intermittent problems as the load drops in and out of the charging circuit, though internal corrosion is not so common with modern batteries.Quote:

i think you need to check the wires condition from the alternator to the battery.
if you test the voltage across the terminals while it is off, and it is enough to start the car. the start the car and test the voltage across the terminals. if it rises to 13-14 volts, then the current is getting to the battery. Have the battery checked like stated. ALSO check your fuse block for signs of burning, arcing etc. There has been a power distribution problem brought up in numerous threads, and with a power distribution issue, weird electrical things can happen all over the car.
