... Yes, i DID use the search function, but i wanted more specific advise on how to remedy my currrent situation...
well, i'm running an electric fuel pump off of my set up (a carbed 306)... however, i think my alternator is holding me back. i checked and charged the battery, even changed it out, but still no improvement...
basically, when i turn on my fuel pump, it's a lower-key hum. when i turn the car on, wait for it to idle, it idles and still makes the lower-keyed wine. when i rev the motor, however, it wines inconsistently, like a "WAH WAH WAH WAH WAH WAH WAH"... not just a straight "wahhhhhhhh"... my theory is that i'm not getting enough juice to the pump. so i took my car charger and hooked it up to the engine start setting (constant 200 amps to start).. the fuel pump, as soon as i turned it on, had a constant, high-pitched, better-sounding noise, and then when i turned it on, despite what rpms it was revved at, it never inconsistently wine.
furthermore, when i turn my headlights on, they dim in sync with the wah wah wah of my fuel pump. however, with the extra juice provided by the car charger, they were as bright as ever and do not dim in the slightest with the fuel pump...
so can anyone figure out my problem? i had it it figured for an alternator. if everyone agrees, can anyone point me in the direction of a cheap (and when i say cheap, please, for the love of god, as least costly as possible - i'm a full time college student, folks
) alternator that will give me all the juice i need...
... the way i see it, i cannot simply do with the incessant whining because this obviously means that at some point or another, my car is leaning out and is in needs of more fuel. i figure i'm losing some serious numbers on the top end because my alternator is ****tign out on the bottom end.
PLEASE mustang guru's, help me out here!
