So I have a 1988 subaru gl wagon and it is having charging issues. As in the alternator is not charging the battery. I have replaced the alternator twice as well as had my old one tested (it tested at 14.5 volts). I have replaced the battery, and have taken off and cleaned all the grounds battery terminals, and plugs to and on the alternator. Whenever I test the alternator output it is the same voltage as the battery. Whenever I rev the engine above 3000 rpm, all the error light come on (charge, break fluid and stop lamp) just like when you turn the car to the on position. Thought it could be the ignition switch so replaced that and still nothing. Any suggestions? I am out of ideas.
