Battery / Alternator / Voltage Regulator problem?

If the problem is seen only when the engine is on , it has to be the alternator.

An easy way to check would be to hook up a multimeter to the battery and see if the voltage fluctuates when the car is at idle. If the engine is raced and the flickering stops , then please have your alternator serviced.

You could just check all connections/main fuses , especially the main wiring coupler at the alternator.

An update on this. I had driven home last week. While driving at Cochin, I suddenly lost the power steering assistance and the battery sign lit up on the dash. Luckily I was at the vicinity of the service center. The issue was with the alternator pulley. The dampener pulley was changed along. The SA thinks that the flickering would be a related symptom.

Hi Folks,
Lately I have noticed that although my Alto LXi runs fine in daytime. No starting problem, good horn sound, etc. , during night when I switch on the lights, there is a whining sound from the alternator and for slightly longer distances some heat fumes are coming from the bonnet. The alternator is too hot to touch. Have checked the battery-no problem there. Voltages during idling and off is within limits also. Any insights? Could the alternator be failing even though it generating correct voltages.

Check the Alternator belt. Some workshops intentionally tighten the alternator belt to get future repairs, you may wish to check this as well.

The alternator in my 10 year old, 1 lakh 58 thousand Swift Diesel conked of yesterday, the battery light was on and the voltage was 12.27 while the car was on, it should show 14 and upwards but not more than 14.4 V

The Denso one which my car has costs a whooping 14700 for replacement, NO way in hell am I going to buy such an expensive part, so the second option was overhaul, which costs 3500 rupees but remove and refitting charges that the Maruti guy will take, gave Ravi Automobiles the go ahead and now the work is being done.

The alternator lasted long but 14700 for a new alternator for a Maruti Swift is just ridiculous pricing. When an entire clutch kit with bearings costs less than 10 thousand rupees, when an AC compressor costs 11 thousand rupees, WHY should an alternator cost this much?

Nahi baba nahi, I am getting it overhauled, since a month or so, the car is sucking the life out of my bank balance, now she will get things fixed whenever it's possible then replaced.

Hello Friends,

Sorry for any mistake. This is my first post on the forums.

I purchased a 2011 Chevy Spark LS Petrol variant ~5months back. This is my first car and took it to learn driving. Its been good so far except one issue. The battery light keeps popping up and immediately renders the horn NOT to function. A local auto electrician found the issue with voltage regulator. Problem is I cannot get this part as its NO longer manufactured. I got one Chinese brand but that has only one connector. Did tried to repair the existing one it but, its NOT completely solved. I am located ~220 KMs from Hyderabad. Any guidance where I can get this part. It was earlier manufactured by Lucas TVS and they have made this item as Obsolete.

Thanks and Regards
Syed

Finally got the regulator from a shop in Afzal gunj Hyderabad. Would be helpful if someone can advise on must have accessories for my spark.
