    Mga tol. ask ko lang. Ung battery ng Series 3 ko eh 5 times na na dradrain.
    New replace battery na enduro na sya..
    Pinacheck ko sya sa Reys Auto Electrical 4 times na din eh wala naman daw ground
    Ang pang check lang kasi nila eh ung tatangalin ung negative wire iiipit ung bulb nila tapos pag umilaw daw un may ground
    Pero duda kasi ako lagi nlng ako na dradrainan ng battery.

    Possible ba ung Diode ng alternator. may nabasa kasi akong ganong post

    Salamat Mga Pre

    pag-andar ng kotse, naka-ilaw ba yung generator warning light? hindi kaya sira yung alternator, o may poor connection, kaya hindi kumakarga yung baterya?
    at mas magaling kung multimeter yung gagamitin at hindi bumbilya..

    I would doubt that it's due to a faulty alternator. I'd rather bet that it's due to something draining your battery.

    3 days? Baka may maling connection lang dyan. But 3 days is a pretty long period so the drain isn't huge (ex. open headlights). What about letting the CASA take a look nalang?

    Para malaman mo kung battery, alternator o grounded, mag try ka boss ng ibang battery, kung hindi siya nadrain, yung battery mo na bagong bili ang may deffect

    Na try na rin ng ibang battery. kasi pinull out sya ng motolite and nag lagay ng bagong battery. but still drain ulit sya for 3 days... wala naman umiilaw pag umaandar at normal ang charging nya nasa 14 kahit bukas ilaw at aircon.

    Sya nga pala. may pinacheck ako... sunog daw ung diode nung alternator.. ask ko kung mag kano papalit ng diode. buo daw. ask ko din sya kung un ang dahilan. di nya matiyak. na observe ko din pag bukas aircon medyo nag dedelay ng konti ung reaction ng engine pag tinatapakan ko gas pedal.. medyo nag didim din pag bukas aircon any idea mga ka tsikot. Thanks

    Kung Diode lang ang papalitan mura lang yan pero ang labor di ko alam.
    Subukan mo na umaandar ang makina taasan ang idle. Habang umaandar tanggalin ang positive cable ng baterya para ang koryente ay manggaling sa alternator. Pag namatay ang makina sigurado yang alternator may problema.

    bali kasi ang lumalabas ok ang charging ng alternator. sinubukan ko na din yan ok hindi namamatay... ang nagiging problem lang kasi alternator din ata ang nag dradrain ng battery dahil sa subog na diode, di ko lang sure kasi pinatignan ko ala naman ground daw kasi di naman daw umiilaw ung bulb... really frustrating lang kasi pag gagamitin ko eh ayaw na mag start i chacharge ko pa ulit sa bahay.

    never disconnect the battery when the engine is running. the surge of the charging system is not regulated and the sensitive electronic components such as pcm, bcm, gps, entertainment systems, digital instrument panel and the alternator itself goes into self destruct mode.
    what you can do to isolate the potential problem circuit is to place a very low current test light or a digital multimeter on milliamps range between the negative battery post and the negative battery cable. read the parasitic drain after the system has stabilized, i.e.; the doors closed, all switches off and the capacitors for all components with memory has been charged. the current should be less than 30 milliamps on the multimeter. if you use a high impedance test light or a digital multimeter, unplug the fuses one at a time until the current draw is at its minimum. the last fuse pulled out and caused the current to drop has the branch circuit that has the problem

    bali ang gagawin ko is after charging the battery, i coconnect ko between the negative pole of the battery to the negative cable of the car.... then dapat 30 milliamps ung readin,, then 1 by one alisin ko fuse then pag di nag drop balik ko ulit then sa ibang fuse naman..
