headlights electrical load

[giancute]

mga sir, (expert sa vitara or electrical)

pansin ko lang na humihina yung blower ng aircon ko kapag nag-on ng headlights... dinig talaga yung difference nung lakas ng blower with and without headlights... i already have installed relays for the headlights... ganun pa rin... what could be the problem? bago pa naman batt ko this yr lang ako nagpalit... mas mataas na rin rating(from stock) ng alternator ko (70A)... tsaka nagdi-dim din lights ko kapag naka-drive and naka-stop (medyo low rpm)...

any inputs po will be highly appreciated...

THANKS!

pa check mo battery. baka mahina na. kahit 1 yr palang.

wala sa battery yan. pag umaandar na ang engine hindi na battery ang nagsu-supply ng electric current, alternator na.

sabi mo medyo low rpm di ba? medyo taasan mo kaya ang idle kahit 50rpm lang and see if it makes a difference. baka sobra baba ng idle speed kasi. kung hindi voltage regulator na yan.

afrasay,

pinacheck ko na batt oks naman...

yebo,

tinaas ko na rpm eh nasa 1K na... kapag on lahat ng load 12.5V and reading sa battery... how do i know kung voltage regulator nga? di ba built in na yun sa alternator?

pwede rin pong maluwag yung belt ng alternator, di umiikot ng maayos so lower power output................

Di naman kaya sa electrical loads mo? Higher wattage bulbs, amplis & radio setup, at AC blower na nakaset sa high.

[Poops]

giancute, measure mo battery terminals pag disconnected. Pag less than 12.5, that means nag di-discharge yan at full load.
Best really is to insert an ammeter between battery and alternator para alam mo kung enough yung juice. Since you're at it check mo rin kung ilang amps ang load mo naman. It's all about current in and out of the battery under various conditions (i.e. open/no load, idle, full load, etc..). From there you'll get an idea alin ang di normal.

check alternator if its giving dishing out the correct amperage. Minsan pag ganyan malapit ng bumigay alernator (I.C or yung mga diodes, rectifier). pwede mo pabuksan para malinis and to check din yun overall condition nung alternator.
