[QUOTE="John in WI, post: 466448, member: 3507"] Lately when deiving my truck at night, I notice the headlights going dim and then bright again. I first checked the alternator and it was pushing 14 volts at high idle, but only 9 at low idle. I replaced it with a new alternator that runs at a steady 14 volts, but I'm having the same problem. The lights are nice and bright at driving speed, but then go dim when I let off the gas or hit the brakes. The battery is less than two years old. Am I missing a voltage regulator or something simple? Does anyone have some tips? Thanks! JW [/QUOTE]
