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.
