How to Know If It Is Only A Battery Problem

[lowslowbenz]

Sus parang CASA. X-Trail sasakyan ko, di pa naman nasira dahil sa pag tangal ng battery habang umaandar.

My alternator conked out three months ago. Pinabaklas ko at putol na wire lang ang problema sa loob so the my trusted electrician soldered it and replaced the bearing and whala!! 900 lang gastos ko.

Yun na nga, naputol ang wire dahil umiinit yun kasi walang load na pupuntahan ang kuryente na kinakarga ng alternator mo, that load I am talking about would normally be the battery. Maaring hindi nga masira alternator mo ngayon, pero pag madalas mo ginawa yan, tanggal ng battery habang umaandar ang X Trail mo, you will know what I mean.

Here's a bit of reading material for your education, (with diagram pa yan) Charging System Basics

I think hindi issue na walang load ang alternator mo. Wala naman problema na wala load alternator, it is just like a genset na nag energize pero wala ka nakakabit pang appliances or load.

There will be an issue kapag grounded (yan ang term na gamit ng mekaniko) and sasakyan mo, the truth is di naman ground yan, meron lang low resistance between sa +12V at GND connection gn battery mo at alternator, ibig sabihin may component ka na nagkokunsumo ng kuryente na hindi dapat based sa specs ng component nya or may mga leaky connections ka (wiring na open, then nabasa at nagkakaroon ng short connection).

Ang pwede mo maging issue sa sasakyan mo kung tinatangal mo baterya na alternator lang tumatakbo ay yung peak and low supply voltage sa sasakyan mo, remember alternator is a generator, affective yan ng speed prime mover, kung sakali bigla bumaba ang ikot ng prime mover say akyatan yung byahe, asahan mo kakapusin kuryente sasakyan mo, at kung bigla naman umarangkada ang sasakyan mo, expect that your system voltage will rise also, wala ka masyado issue sa increase sa system voltage kung masyadong maganda ang voltage regulator mo.

That is correct in a sense bro.,- because the vehicle battery(and all batteries for that matter) acts as a natural voltage regulator....

I hope that the alternator is not connected directly to any of the vehicle accessories,- if yes,- then you have a real problem....

Correct ko lang.

1. If walang load, no reason for the wire to get hot. Current runs in a loop, no loop means no current, but there will be always voltage. Ohms Law, I=V/R
2. Battery acts like a natural regulator, in a certain way yes it will as long as kaya nya pa I-tolerate yung excess na voltage na pinatong sa kanya.

Ganito yan, magparallel ka ng 12V supply at 11V supply, yung 11V ang mababasa sa meter mo at the instance na hindi pa sumasabog yung 11V mo or tolerated nya pa ang source.

Hehe, kung ganyan ang pag-kakaintindi mo sa pinakita ko na link at sa sinabi ko. Wala na akong argumento dyan.

It all sounds greek to me

But geek talk is ***y

I really hope it's just the battery since it's 4 years old and has been recharged numerous times already. I'll have the AC fixed too. I hope I can do all these in one day I can't help but think nagtampo kasi may buyer na tumingin last week Naiiyak pa rin ako thinking that I have to sell my Corolla soon.

[siopaonatoasted]

Di ko kailangan yung link, it is just a simple Ohms law, kung wala kang load, paano ka magkakuryente?

The mere fact na naputol wire mo at may tumakbo na kuryente, ibig sabihin may load ka, di nga lang yung baterya kasama sa load mo.

Kung di mo ginagamit pero mabilis discharge at sa tingin mo ok pa baterya mo. Pacheck mo wirings mo.

Parasitic Load ang tamang term.

Safe yan sa old school, mechanical-type controls. Malaki tolerance sa voltage spikes/changes.

Yun mga de ECU at efi, pwede mo isugal pero you have been warned ika nga sa manual.. Pede masunog electronics kung hindi maganda regulation.

Yung battery acts as filter/ regulator, parang malaking capacitor.

O, wag kayo mag away. Baka lalo maguluhan si TS

Cathy, why not ung BF mo nalang pasikasuhin mo nyan para ma test mo rin kung maasahan. Okaya bili ka ng jumper-wire sa ace tulad neto (kabibili ko lang kanina for my a/t apv)

Kabit mo sa Altis. Then crank mo mga 30mins at 1.2k rpm. Tangalin mo jumper once na kumarga na, then from there pede mo gawin yung isolation methods na nabanggit dito to determine if battery or alternator problem.

Delikado kasi kung ililipat mo yung battery ng Altis, syempre hindi ka pede mainitan gagamit ka ng aircon. Baka ma-drain e di 2 cars na ang disabled.
Yun jumper-wire magagamit mo pa in the future, malay mo masiraan si Uls ikaw tatakbo to the rescue. Lalo ka magiging cowboy nun.
