kagabi nga pala pagka start ko ng makina (4d56 diesel adventure) may maingay na squeeking sound kapag inaapakan gas pedal(binuksan ko hood at suspect ko galing sa alternator) , kapag inaapakan din gas pedal ay lumalakas ang headlight..
e nabasa ko nga tong trick, ginawa ko kanina umaga, inistart ko engine tapos tinanggal ko negative terminal sa battery, tapos after 30 seconds siguro, AYUN! namatay bigla ang makina.. tapos inistart ko ulit, ayon sa amp meter gauge ko, nakalagay lang sa zero kahit na naka ON ang headlights at radio ko tapos ayon, hindi na nagcha charge ang alternator nasa zero lang..

ano gagawin ko mga sir???? help..
