What are signs of a bad alternator?
Im not 100% sure, but my new Dmax compared to my old one has this deep whining sound that goes with the rpm of the engine, to me it sounds like an alternator, i remember that sound from one of my old 1500 gassers. My old dmax never made this sound. Its very inoying, its not the turbo i know that sound. the voltage is over 14, any ideas? Also i havent had a chance to use the A/C yet. could it be that making the noise if it was bad?
