#1

The vehicle has 100000 on it. The porblem i am trying to solve is the alternator gives a good out put at 3000RPMs. Below that the battery will go dead.



I am used to the fact that an alternator has an output or not.



I am suspecting the grounds may be corroded before I replace the Alternator


#2

Have the battery checked also, it may be fried.


#3

Did that and it checked out good.


#4

By all means check the grounds first, but yes an alternator can provide a low output. It’s an inductive device, and if some of the windings are bad the induced peaks will be lower.
