While driving a few nights ago I noticed after a short period of time my headlights and gauge lights became very dim then, went completly off. My volts are usually at 11 1/2 but when the lights are on it goes down to 9 1/2. I replaced the alternator with a 100 amp alternator, thinking that was the problem but, again it happend tonight. I have an electrical fan, msd ignition, radio, and electric fuel pump. The stero has also been going on and off when I put my turn signal on. The speed seems to also effect the headlight brightness since when I'm driving at around 75 mph they go out but, when driving 35 mph they stay dim. Any suggestions would be greatly appreciated!!!!
