    kahapon pa ako nagse-search eh, hindi ko pa ri makita.
    kasi nabasa ko na yung 'diy' na yun dati pa.

    anyway, maitanong ko na lang ha.

    how to check kung aling accesory ang may shorted/grounded na
    wires? yung nabasa ko nun is tatangalin (ata) isa-isa yung mga fuse
    or something na parang ganun eh. hindi ko na maalala. kaya hindi
    ko rin siguro ma-search ng tama.

    kapag umapak ako sa preno, bumababa ang rpm (nagdi-dim din ang
    gauge lights). at kapag naka a/c pa ako (at naka ilaw pag gabi)
    nagbi-blink ang headlights.

    tulong naman po diyan mga masters . . .

    try mo search sa internet "ampere draw test"
    or follow these:

    tester required:
    DVMM (preffered) or 12V test light
    disconnect neg bat terminal, wait for at least 20min (kung meron mga control modules ang car mo to put them on sleep mode). using the DVMM on ammeter mode (set mo nuna sa higher amp setting para hindi mo masira DVMM mo in case sobrang laki ng amp draw) connect mo yung isang lead sa battery terminal yung isa naman ay sa neg cable. continue trying hanggang sa milliamp range hangang makakuha ka ng reading (acceptable for some models is 5mA) kung mahigit 5mA (abnormal draw) then remove mo yung fuse one by one hanngang makita mo yung nag cause ng draw, repair the circuit that caused the draw. CAUTION: while in mA setting never kang mag "on" ng kahit anong system sa car or you'll say bye-bye sa DVMM mo.
    or test light method, just same setting pag bright ang ilaw may malaking draw tanngal isa isa fuse hanggang mamatay ilaw test light.

    san ko ilalagay yung dial? ngayon sa ganito nakalagay yung
    dial ko. (like the one sa baba, DCV nasa 50)

    set mo sa 10 amps ang amp meter mo kung meron pero sa picture parang wala.connect the positive probe of the amp meter to negative battery cable at negative probe to negative battery terminal.pero palagay ko di mo kailangan gawin kasi obvious naman na shorted sya.check mo daw muna yung brake lights baka pundido na.

    wala naman pundido na lights.
    i went to Wizzards kanina. wala naman daw grounded.
    ang tinurong culprit is yung idle-up (IACV, since it's a civic)
    haay... problema pa rin.

    sinabi ba nila sa iyo na nagperform sila ng current draw test?at sinabi ba ang resulta?.itry mo na lang daw ieliminate ang problema baka sakaling matulungan ka nito.

    with the key on engine off;

    -apakan mo yung brake,may changes ba?
    -turn on all lights,may changes ba?
    -yurn off the lights at turn the a/c on,may changes ba?

    key on engine running;

    -apakan ang brake,may changes ba?

    -release the brake pedal,turn on all lights,may changes ba?

    -turn off all lights,turn the ac on,may changes ba?

    Baka po bad ground lang. Check nyo engine or chassis ground voltage drop.

    key on engine running;

    -apakan ang brake,may changes ba? meron konti (baba konti idle)

    -release the brake pedal,turn on all lights,may changes ba? meron konti (baba konti idle)

    -turn off all lights,turn the ac on,may changes ba? sobra! (baba idle)

    additional info... with engine running pag pindot ko ng power windows lalo na pag nakasara na yung window, baba pa rin ang idle pero konting konti lang.

    Maaring ang ground wire ng headlights,brake lights at gauge lights ninyo ay magkasama sa isang bolt. Sa may engine bay kalimitan may 2 or 3 black wires
    na nakabolt sa body. Puwedeng sukatan ang resistance ng bolt head at negative terminal ng battery.

    teka nga pala, do i have to use the voltmeter for this? if so, saan ko
    ididikit yung mga probes?

    hindi na kailangan,tulad ng nasabi ni inekem,icheck mo muna yun,check for corrotion,bad connection,pati na rin sa battery terminals,or pwede mong gawin ito,hanapin mo yung fuse ng brake/stop lamp.malamang na nasa under hood fuse box yan,tanggalin mo at paandarin mo ang makina at apakan mo yung brake pedal,tingnan mo kung may changes ba.

    okidoki. salamat sa mga tulong ninyo ha. wag sana kayong mawalan ng gana sa pagpapayo ninyo.

    try ko i-test yung grounds, batt terminals, brake fuse tonight.
    btw, kaka-palit ko nga lang pala ng batt terminal. yung tig P50.

    another observation, kapag nilagay ko na sa D mas malaki ang binababa ng
    idle. kaka palit ko lang din ng ATF this year.

    update ko this thread after ko magawa.
    wish me luck!

    i tested the grounds last night. maayos naman mga sir.
    eto ang ginawa ko pa, i adjusted the idle as per user manual.
    bring up temp to normal, patay makina, tanggal 2p connector sa EACV,
    bukas makina, adjust ang idle screw, tumaas naman, patay makina,
    reset ECU, kabit 2p connector sa EACV, bukas makina, check idle (sa tach),
    medyo mababa pa rin pero hindi na yung halos mag stall ang makina.
    bukas mga ilaw, a/c. ayos pa rin, hindi na nag stall or nag blink mga lights.
    kumbaga, same na ulit ang 'ugali' before magluko (yung nagbi-blink at namamatayan).
    sa ngayon wala akong pera eh. so ipon/tiyaga muna ako dito. and then
    ipapa-tingin ko na ulit yung EACV at pa check kung may vaccum leaks.
    until then tiis-tiis muna sa ganito. wag lang mamatayan ulit. (fingers crossed)

    update ko this thread pag naipatingin ko na ito.
    salamat ng marami sa mga tulong ninyo.
    mabuhay ang tsikot!

    how do i do this ground voltage drop test?
    To do a voltage drop test, you create a load in the circuit that's being tested. Then you use a digital volt meter (DVM) to measure the voltage drop across the live connection while it is under the load. Voltage always follows the path of least resistance, so if the circuit or connection being tested has too much resistance some of the voltage will flow through the DVM and create a voltage reading.

    If a connection is good, you should find little or no voltage drop and see less than 0.4 volts for most connections, and ideally less than 0.1 volts. But if you find more than a few tenths of a voltage drop across a connection, it indicates excessive resistance and a need for cleaning or repair.

    Set the DVM into a range of 20V. While the engine is running, put a negative probe of DVM in a negative terminal of the battery and positive probe to engine body or chassis. The reading should not more than 0.10V. Do this with or without electrical load.

    san ba shop na medyo marunong mag trace ng mga ganyang poblem?
    my civic 96 same na same problem, sana may ma rerecomenda kayong electrical shop para maayos na tong tsikot ko ty

shorted/grounded ?
