At first it only happened when I got close to 5000 RPM's, but now if I get above 3500 RPM's the battery light will start to flash, then if I keep into the gas the battery light will go solid red and if I stay on it, it will kill all the power in my vehicle. If I let off the gas and let it shift to the next gear, It goes off, and at normal cruising speed it doesn't come on at all. Any help would be great. Thanks!
