Help!!! Battery problem, alternator problem, or anything else? (for corolla gl '90)

**manley** · July 10th, 2007 06:49 AM

Just want to ask for some inputs/advise from those of you who might encountered similar problem...

My car is corolla gl '90. 3 months pa lang to sa akin. Parang hesitant na akong dalhin sa mekaniko na wala pang idea kung ano ang sira kasi madalas padagdag ng padagdag ng kelangang ayusin pag dinadala ko sa kanila.

The problem is that recently, angtagal mawala ng red light ng battery. Habang nakailaw, parang palyado ang takbo ng makina to the point na namamatay pag nagmenor ako. Wala namang problema sa pag-start. After a few kilometers at nawala na ang ilaw, smooth na ang takbo. Kaka-tune-up lang nito last month. Inadjust din ang idle-up. Sabi ng mekaniko that time, okay pa daw naman ang battery. Yun ang kinakatakot ko... baka kung ano na naman ang makitang sira pag nagkataon.

Ano kaya sa tingin nyo ang root cause? Battery, alternator, or anything else? Siguro better na rin if you can recommend to me a mechanic na expert sa corolla gl. Preferably yung malapit sa Cainta area kung meron.

Thank you so much in advance.

Manley

Check battery ground cable for loss connection from your batt terminal to engine bay or chassis and also your alternator wire. Look for any suspicious loss wire clean theme and tighten them all up. Seems like your car grabbing all the electrical power up to the limit whenever you step on your barke thats reason why your hessitant at first.

pag umilaw ang battery warning light sa dash, usually charging system problem yan.

aside from what v6dreamer suggested, check the alternator belt, it might be loose causing it to slip. when that happens the battery indicator will light up.

have the alternator check sa mga battery shop esp when the battery indicator is lit up. it could be that the alternator is not charging properly, over charge or under charge.

Nangyari na din sa akin yung problem ng car mo. ang culprit ay ALTERNATOR low charging, pinalitan carbon brash ng alternator medyo maiksi na kasi. also to detect kung battery or alternator problem you can try this step, disconnect either possitive or negative wire of your battery while your car engine is on, if the engine will stop, alternator might be the problem, if not your battery might be defective.

Check first the alternator terminal, belt condition and tightness, voltage regulator(if equipped).

+ kay ukay, n while na ka disconect ung terminal pwde m series ng VOM ng mkita mo charging rate ng alternator it should be around 14-17volts (depende sa amperes ng alternator mo)

It seems that the problem I had with my car is just one of the by-products of worn out piston rings... Explanation ng mechanic is that mahina ang power kaya parating naka-red ang battery indicator sa dash board. This is because of loose compression. Early symptoms lang pala yun ng worn out piston rings. Pinacheck ko kasi ang battery and alternator sa motolite ok daw naman. Fuel consumption suddenly gone crazy at naging mausok ang tambutso!!! Nangingitim yung spark plugs kahit na bagong palit pa lang. Yun ang indication na di na pwedeng pagtagalin na hindi ipagawa kasi baka abutin ng need to overhaul. So the solution is replacement of piston rings, valve seal, cylinder head gasket, and change oil. Sinabayan na rin ng linis ng carb. So far so good. Around 3,500 for the parts (piston rings, valve seal, head gasket, oil, filter) and only 2,000 sa labor. Inabot ng 4 days sa shop.
