weird electrical problem

[revoGSX]

better have the alternator checked.. baka po hindi kaya ng surplus alternator yung load.. pa-check po ninyo kung kaya niya talaga mag-bigay ng 90A continuous load .. hindi ko alam kung paano ito i-test.. baka sa mga battery stations eh libre..

kung meron po kayo tester eh check po ninyo yung battery voltage kung mag-drop ng less than 12volts..

sa pagkakaalam ko po eh... ang battery ang bahala sa pag-start ng engine ..then the alternator should take care of all your electrical components... check din po ninyo yung rpm.. it should not go below 800rpm with aircon off at 1000rpm with aircon on..

kung may marunong kayong Electrcian have it check.same thing happened to my cousins starex nagpalit ng head unit nya at pag nag high rev sya meron kang maririnig na ovious sound then yung windows nya kung pag pinagsabay nya itaas both side namamatay yung HU nya..may nilagay yung electrician na metal coil dun sa batery na parang ginawang ground(Noise suppesor tawag nila sa principle pero yung metal coil forget ko tawag dun tanong ko bukas)..nawala yung ingay ng HU nya pati yung prob nya sa windows nya

Check mo grounding wires mo, dapat may grounding ka sa kaha and sa engine body, baka may loose connections

[afrasay]

mabigat kasi ang load sa alternator/battery when you are raising your windows as against when your lowering it. check your alternator baka overrated.

yeah.. the alternator is overrated at 90A since 80A yung stock. pero malaki yung difference sa idle when it kicks on. i'm pretty sure hindi 90A ang draw ng motors. anyway will have it checked this weekend.

also regarding RPM.. hindi 800-1000rpm ang idle. it's more like 600-700rpm no A/C, 700-750 with A/C. normal naman daw yun for this engine. pero malaki ang "roughness" ng engine when loaded yung alternator.. doesn't seem normal kaya pa-check ko na.
