I'm Awesome
1996 K1500 5.7 w/105 amp alternator.
After driving a while with the motor fully hot, especially now that it's a bit warmer outside, my volt meter gauge drops quite a bit below the 14v mark, getting close to the next large hashmark on the volt meter. It was doing this last night, and when I turned on the headlights it dropped further on the gauge. I have not put the multimeter on it when it's reading low with a hot engine.
This morning, with the truck outside and temps in the high 30's I start the truck and the volt meter gauge reads a full 14 volts, my multimeter reads output of 14.6, and with the engine off the battery reads 12.6 volts on the multimeter.
My experience has been a alternator eithers works fine or it quits working period.
Usually a regulator or rectifier just quits at once rather than a slow death in my experience.
Could the brushes be wearing out?
