    Mga ka tsikot, gusto ko lang mag tanong about dito. Nabasa ko lang rin kasi ito sa ibang site. Ask ko lang if this would help the battery charge well at kung malaki ang benefit nito on the long run? At paano ba ito gawin? I never tinkered at automotive electronics. at balako ko sana gawin muna sa owner namin. Opinions and suggestion are very much welcome! :D

    wala naman po masama sir sa pag add ng additional grounding nang sasakyan...
    so additional wires for grounding would be a simple and inexpensive upgrade...

    personally i add additional grounding wires and grounding points,
    but i only use OEM surplus wires na mabibili sa mga nagtitinda ng engine and wire harness...
    its usually black with yellow stripes na sobrang kapal. 0 gauge ata yun. mas maganda if meh kasamang OEM battery clamps... kasi pag oem harness pure copper ang battery clamps...

    pag sa mga auto supply manipis/underrated at hindi pure copper kaya malambot at mababa diameter ng strand ng wire, so ma defeat lang purpose.

    gauge 0-4 would be ideal...
    dagdag ka from battery to chassis, chassis to engine, bolts near the alternator housing to negative clamp.
    gamit ka na lang mga copper eyelets para mai-secure.... DIY hehe...

    Salamat sa response sir miko101130. :D

    May nabasa ako somewhere sa net at ganito yung installation ng Big Three.
    -chassis to engine block
    -chassis to battery negative clamp
    -alternator positive to battery positive

    Correct me if mali ito or kung ano ang tamang pattern. Ito kasi yung nakita ko. Then AWG #4 wire yung gamit. And okay lang ba na kahit magkahiwalay yung both sa chassis na ikakabit? Yung sa owner kasi namin meron na siyang chassis to engine block yung dalawa na lang yung wala at AWG #4 yung ginamit na wire.

    why po? are you experiencing electrical problems?
    i subscribe to the juan tamad creed of "if it ain't broke, don't fix it".
    heh heh.

    No problem naman. Kung may room pa for improvement na easy to do, why not do it? Di kasi ganun ang mindset ko na kung kailan lang may sira dun i che-check.

    yung nasa alternator output na positive that goes to your positive clamp, wag mo na baguhin unless naputol o nabalatan...
    the alternator positive does not require a very thick wire like those for the starter line...

    the only reason kaya ang kapal ng wire na nasa battery poles ay dahil sa starter...
    once nag click yung starter solenoid your starter will draw around 200-250 amps!... most alternator only max out at 90 amps.

    the largest wire on harness for regular wiring is about gauge 4...

    just add ground wire from gauge 0-4 sa batter negative to any part of your chassis, then add from chassis to your engine,
    wag kalimutan gumamit ng copper washer o anodized na bolt para hindi ma-corrode later on yung pinagkabitan ng grounding points.

    Personally, replace the whole thing if you're already doing it and replace it with 4AWG. Hindi lang naman yan sa matter of kaya or not.. but it's a matter of optimizing the flow of electricity by reducing resistance. Will it cost more? Yes. But chances are if you already done one or two of the procedure, doing everything won't hurt your wallet.

    Just remember to make sure everything's connected and installer properly.

    I already got the items needed kaso hindi ko ma determine yung positive line ng alternator ko. Three wires kasi siya then two wires are thinner while the one connected via nuts and bolts are fairly thick. I was thinking of going in a alternator shop para ma check nila and is it okay na wala ng fuse yung sa alternator positive to battery positive connection?

    yung nakakabit sa likod with a large bolt is the positive one, covered by a red rubber grommet yun..
    ito din ang pinaka malaking wire among the three na meron ang alternator.

    dapat may fuse sir ang positive line nang alternator going to your main fuse line.
