Alternator

[romuel]

nais ko lang pong malaman kung ano sira ng alternator ko. kasi yung aking light indicator hindi na umiilaw kahit on or off yung susi,
ang voltage reading pagnagrev ay maximum of 13.8

may nagsabi sa akin na palitan ko lang daw yung regulator chip dahil yung lang daw sira. tama ho ba yun?

pero ang idea kung regulator lang sira, ipa convert ko na lang sya sa conventional type (new era brand) since na alam kung parehas naman sila ng function. uubra din kaya yung convertion?

sir baka naman busted lang ang light ng panel board nyo yung batt indicator? kasi on & off ayaw umilaw? kung sira ang alternator pag on ng engine iilaw ang batt indicator tama?

[romuel]

di naman po busted yung bulb, try ko test yun, okay naman, kaya lang ako nagtataka, may charging naman sya and it range 12.5-13.8V, tapos yung indicator wala talagang ilaw from the time i on the switch even i engine was started.

halos one week ko nang gamit na ganito ang sitwasyon.

baka may idea pa po kayo.

sir mukhang mahirap yan btw isang lingo ibig sabihin hindi nadidiskarga ang battery so it means na ayos ang alternator mo? pwede ic chip nga ang may sira

kasi yung sa isang van ko pag start ko naman laging naka ilaw ang battery indicator pero once na pinitik ko lang ang gas pedal mawawala na sabi nila sensitivity daw ng IC chip yun

[romuel]

maraming salamat sir, try ko maghanap ng IC Chip

help naman

kagabi nga pala pagka start ko ng makina (4d56 diesel adventure) may maingay na squeeking sound kapag inaapakan gas pedal(binuksan ko hood at suspettya ko galing sa alternator) , kapag inaapakan din gas pedal ay lumalakas ang headlight..

e nabasa ko nga tong trick (tanggal negative terminal habang naka idle ang makina), ginawa ko kanina umaga, inistart ko engine tapos tinanggal ko negative terminal sa battery, tapos after 30 seconds siguro, AYUN! namatay bigla ang makina.. tapos inistart ko ulit, ayon sa amp meter gauge ko, nakalagay lang sa zero kahit na naka ON ang headlights at radio ko tapos ayon, hindi na nagcha charge ang alternator nasa zero lang..

ano gagawin ko mga sir???? help..

[romuel]

much better if could brought it to alternator shop.

but my suspect is the ic regulator,

[aga_cruz]

XT7 wala bang naka indicate na naka ilaw sa panel board nyo sa loob? IC or carbon lang naman ang madalas masira sa alternator

The battery light should come on when the key is in the "on" position with the engine not running, then it should go out when the engine starts. If it is not on when the key is in the "on" position and engine is off then the light is malfunctioning.

XT7 that is not why your battery is not charging I just wanted to verify that this is how you diagnosed the cars battery light.

Does the car run for awhile then die or does it run until you shut it off and then not have enough power to restart? XT7 you did the "poor man diagnostic way" by removing your battery cable. You wont believe what happen to your car if you did that again.

If it will run until you shut it off and then not restart the problem is the battery (even if it is new).

If your alternator fails, both your running car would drain the battery very quickly and then the ugly sounds....TIC TIC TIC when try to re-start, it dies out. If it is draining the battery while it is running the problem is your alternator.

That is the alternators only function. It supplies power to replace what energy was used from the battery when the engine was started and supplies the vehicle with all its electrical power when the engine is running.

The only reliable alternator test is to start the (idle only) car and check the voltage at the battery. It should read between 13 & 14 volts. If it is less, your alternator is not providing enough power.
