    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.

    with the key on engine off; (try ko to gawin tonight)
    -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?

    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.
