Battery or Generator Problem

[sfazam]

On sunday morning (11'o clock) when I tried to start my car on CNG, it wasn't. Just only a sound of tick-tick like problem with "self". Battery was seems to be right b/c headlights and horn were working properly. After "dhakka" start, I took my car to electrician, with out checking car with any instrument, he said that problem is with battery and it's cells seems weak.(he just opened the place from where we pour water in battery). Since battery was under warranty so I took my car to battery shop. They checked it properly and said battery is alright and generator is not providing current properly to battery. BTW now there is no issue in starting car and even I started my car in Monday morning (6:45 am) without any issue.

Now I am confused that whats the actual issue battery or generator? Can anyone suggest please.

First Electrition said that it happen in winter that car won'r start but why car was started on monday and not on sunday.

Only one point is clicking in my mind that generator is not working properly when I use headlights and without headlights since there is less or no load that's why it can charge enough that car is getting started next time.

Brother, your batter and generator is OK. Its just that the Battery Terminal Wire wasnt tied up properly.

So, Now worries!!

[sfazam]

I guess too.... but i noticed that battery & oil indicator goes dim during starting the car. I have little experience in all these but my understanding is that;

"battery will work near to be ok without usage of headlights but if i use headlights then it can be an issue. i guess generator is producing low current" Your comments required.

Also please suggest me good, reliable car electrician between sharah-e-faisal (nursery) to malir.

invest 600 rupees, someone in lhr is sellin a solution that re-enhances its life.

if the generator has any issue, drive a car on low rpm, for around 30 mins, with ac and music player and lights on, after 30 mins, see when u honk, if ur music stops for a sec, change ur generator..

else

goto any electrician and get it checked. they gonna use a simple meter to see the generator output...

i have also the same problem. my santro car starts sometime but some time it is not starting. lts horn, and other accessories like cd player working properly, but sometime its remote can not stop the alarm and lock or unlock the vehicle. when i start my car on dahaka then it starts and after some driving its battery get some charge then it was start on first self for 3 times but then again when i came home, on next morning the car again refused to start. again dahaka start. then i took the battery to battery shop the guy checked it then told me that one cell is damaged, so the battery should be replaced. i told him to put the battery on charge it the shop. after 2 hours of charging (he connect the -ve and+ve terminals with a wire and get a spark after charging, so i am confused y he did this? i think it was again discharged by doing this, i also discuss with him but he said that it is just to check either the battery got current or not) so after this the car did not start again. the +ve terminal side of the battery is also swollen. a friend told me to check the generator. now i decide to purchase a new battery. the old is 48 Amh. which battery is good and what is the price? and what will be the price of my old battery to exchange with a new one. ANY SUGGESTION PLEASE

[Jajja1]

I also feel the same problem. My mehran is also creating tension while starting in morning. I got checked battery( which is only 2 months old), generator, current, self etc.... every thing is running fine but even then it takes DHAKKA in morning. During whole of the day it works fine on just half self.. I m not getting what its prob is.... any one comment/ suggest plz..
Dear horse rider... Exide and AGS are good batteries and cost about 2700. if battery is replaced with old one then less Rs. 400..

[Horse_rider]

dear brothers i have installed new battery EXIDE CNG 48L in my car on Saturday evening. he charge Rs 2600, less Rs 400 for my old battery now It is Ok to start my car in morning. Thank you all.
@jajja1 brother you should check the belts of generator and other accessories to insure that there is no friction. also tight your battery terminals and apply petroleum jelly on the terminals. also discuss with your machanic he will suggest you better. if any other member have the idea please guide Jajja1.

[bluespark]

need to check battery,also ask your electrician to check for potential leaks.SHortage of circuit.Try removing battery terminals at night and reconnect them next morning.If your problem is solved then you have short circuit some where.

[smartboy_am]

maybe your car's self is weak.......

[Proverbial_Slang]

Bro, check the generator voltage on idle and at 3000 RPM's. Also, check the voltage of the battery after disconnecting it from the terminal wires. That would give you a more accurate picture.

[Jajja1]

Dear Brothers... thanks 4 ur replies... I got checked generator which is working well, battery is almost new and working well, got repaired bushes of self, coil is also new, battery terminals r also good fitted... but i dont know even then why it creates probs in starting in winter mornings.. however now i hav started to use petrol while parking and starting my car.. on petrol, it starts but after a long self....

[Jajja1]

One thing more, i hav also got checked the short circuit of current, and also once checked by removing one terminal at night.. but all in vain...
One prb may b... My battery is of brand "National" 45 Impr.... can it b a problem ? even it is only 2 months old.....

I changed my mehran car battery last month. but it was not charging properly and electrician directly connect generator to battery. Generally when car switch off, its battery show 12.34 Volt, and at max RPM it goes to 12.7. My question is whether is it right to connect generator directly to battery, by bypassing the rectifier like device.

Plz guide me.

check ur generator voltage drop in full load,on idle any gen will give u 14v.if u xperience unstable rpm as well then ur gen definately needs to be changed,other wise its the battery.

[jz]

ur gen should perform at its peak at around 3k revs,how ever 12.7 is low output even with the engine on,ur gen can surely be weak,check my above reply to check ur generator.

Winter in Karachi.....lols......
Your terminal might be loose or salts deposited on them. Mechanic must had moved the terminals and your battery is fine since then. Enjoy your ride

[Motorist01]

Currently no salt is on the battery terminals, because the battery is new one. My electrician actually disconnect the original wire from generator, as he claims that this wire is heated up and connect generator directly to positive terminal of battery. Do the mehran has any sort of rectifier (a device used to stablize voltage from generator, as i learn from browsing that replacing this device solve the low voltage issue).

[Xulfiqar]

The rectifier diode bank is internal to the alternator - the stud sticking out where you tighten the heavy cable is the end of the rectifier plate, the voltage regulator is screwed on it and is connected to the slip rings of the rotor via carbon brushes.

What you need to test is firstly the battery standing voltage after letting it rest for 1 hour, you should see 12.6V which means the battery is 100% charged, at 11.9V the battery is fully dead.

Now start the engine and let it stabilise - check the system voltage - it should be near 14V constantly, under load too. If its low, use a jumper cable to connect the alternator main to the battery positive, If that does not help add a ground to the alternator casing. If that does not help make sure you get a good strong 12V supply at the "on" wire of the voltage regulator.

Also check the two fuseable wires on the battery - if they are bad or weak replace them with new ones or install fuses in place of them.

Thanks for reply, during the diagnosis of the problem, my technician jumper the alternator to battery and engine pick suddenly change indicating the old wiring has some problem, so he directly jumper alternator to battery and disconnect the old wire to alternator. but still it is not giving me 14 volt at max rpm. Therefore my battery generally have voltage of 12.4 V, and at night drive if i turn on indicator after head light and radio on, my radio is going to switching off ,indicating low voltage.

build a new generator charge cable wiring harness, use good quality cable - not too thick though. Also check the fuse links on the battery positve posts, they look wiring plugs, they are actually fuses - replace them with new parts. You can buy them at suzuki showroom parts departments
