I've had trouble in the past with alternators in my car. I replace the original (came with the car and had the Saleen pulley so I assume original) when I started having fuel pressure issues earlier this year. The second one crapped out when I got it back from the fuel pressure fix. Tested bad output. This time the battery light would flash but then go off after the car warmed. I ran a datalog and it always charged around 13.5-13.7 volts no matter what the light was doing. After driving awhile the light would come back on and off but I didn't log it. It seemed to get a little better when I manipulate the alternator connector until today. The light wouldn't go off so I plugged in the tuner and watched the voltage. At speed it was anywhere between 11.3-11.7 volts. I got off the interstate to see if the connector may have worked lose and the voltage came back up to 13.5-13.7. Once I got going the voltage would drop again and I noticed that anytime the RPM's were above 1700 the voltage would drop but running below 1700 or at idle the voltage would come back up to 13.7. Could that connector be the cause of the voltage drop? It's strange that it would immediately drop once I got above 1700 RPM's. Is it also a possibility that I need a stouter Alt since this car is built with a little more boogie in it? Anyone pushing more HP and needed a heavier alternator?
