Re: alternator problem 1996 blazer
10V says the alternator is not charging, voltage should be approximately 14 volts with the engine running. Fully charge the battery before starting the engine, then test the voltage. Is the red battery icon on the dash illuminated? The 10gauge wire on the rear of the alternator must read battery voltage at all times. The brown wire should read battery voltage when the ignition is in the RUN position.
