Technical Question about the Ammeter

[jick.cejoco]

mga kabayan,

tanong ko lang about sa Owner Type Jeep, ok pa ba yung kapag nag-sswitch ako ng headlight tapos yung ammeter ko goes on negative side, something like -10amps at idle? pero pagni-rev ko napunta sa zero? pero kapag wala naman headlight, something like parklight, foglight and stereoweak is just on, ok naman..nasa above zero range yung ammeter reading...ano kaya problema? battery? low ampere rate of alternator? or should I change my headlight into a low wattage..old school pa kasi yung headlight niya e yung bilog na sealed beam buong headlight assembly pa talaga, hindi yung type na may seperate bulb.

before you embark or go deeper into the jungle on a wild goose chase, make sure that your ammeter is not miscalilbrated, broken or is not properly connected. try measuring the current with a more precise instrument, perhaps a digital multimeter with inductive pickup or a clamp on inductive ammeter. the generic ammeters like rox, lucas, autometer and other brands gets stuck or sluggish over time. heat, sunlight and age makes the movement of the needle difficult. if the ammeter is connected next to a magnet, the magnetic field interferes with the true indication of current. verify the current with another known good working ammeter first.

z.F, ano ba ang wattage rating ng sealed beam headlight na nakakabit sa jeep?

the picture the TS sent is that of 2D1 sealed beam headlight with an average of 2.5 amps each at high beam. different versions may vary slightly between incandescent and halogen type but the stable average amperage is less than 3 amps.

So the wattage is around 35 per sealed beam, I don't think changing the headlamp will fix your problem.

check muna alternator, baka mahina na ang charging.. probably due to carbon going bad..

sir ok naman yung charging ng alternator niya, napa-check ko na po with multi-tester sa aking trusted auto electrician, while at idle, normal naman..above zero range yung ammeter ko, maganda pa daw ang charging...kapag full charge na yung battery, stable at zero na siya..kayang-kaya niya yung mga electrical load like stereo, parklight, interior lights..pero yung headlight, dun lang talaga nag-ffluctuate yung ammeter reading, goes slightly below zero(going negative na)..sabi pa-check ko daw wiring nung headlight baka daw may loose connection at additional nga pala, yung headlights swith ko rin nga po pala is wala sa ayos, pagnag-pass by ako di nailaw, pagnaswitch ako into dim, wala pero paghigh meron..hinala doon rin po ang cause nun, wala sa tamang arrange yung headlight switches, btw, nasabi din sakin nung dating may-ari na napa-rewire niya na yung OTJ 5 mos. ago,
