Last year I bought a 93 nissan 300zx 2+2, it just hit 131,000 miles. Last month the alternater suddenly went out, so I got a new one and my dad put it in. Ever since the new alternater it has been running pretty rough, and it has a terrible screech when I start it and sometime when I drive it. What should I do to fix this. There's another problem too, when I put my foot on the gas the headlights brighten and the heating/air cond unit and radio goes completely off then when I brake to about 1000 rpms it comes back on and the headlights dim. I've checked all the fuses and the battery. What do you think the problem is?
