I have a 1992 Ford F150 with the 4.9 and 117,000 miles on it. I just replaced the alternator and while test driving the battery light came on and the truck started to die down. I was able to keep it running by feathering the accelerator, but when i would turn on the lights the truck would die down and when i turned them off it would rev back to normal. What could this be?
