Tonight I kept my 2006 passo idling for about 20 minutes with AC on. When I drove for about a kilometer afterwards, most of the electrically powered accessories started to behave intermittently; ABS, EPS, Overdrive and voltage lights started to flicker ON and OFF, steering became hard and brake pedal became hard and sluggish. The tv/nav Unit's screen also started coming on and going off in short intervals.
I stopped the car, switched it off and when tried to restart, it won't budge. The battery had completely drained. I had to tow-start the car's engine. I drove all 6 km to my home with headlights and AC off, however, when i switched off the engine and tried to restart again thinking that the battery would be charged now, it again did not start. Did not even take self.
I again tow-started and this time noticed an abnormal purring sort of sound. So, does this mean my car's alternator / generator is misbehaving or is the battery dead??
I am located in karachi. Would really appreciate guidance and advice. Can someone please point me to a good electrician? I live at PAF Base Faisal.
Thanks in advance.
