Alternators

One of the reasons your Acura may not start is that the battery is dead. However, you shouldn't just go out and replace the battery – it may be fine. If the Acura alternator isn't working properly, it will not charge the battery. If the car starts when you jump it, test the alternator with a voltmeter. Put the voltmeter on 12 volts and touch the positive cable to the positive battery terminal and the negative to the negative battery terminal. If the engine is running, the car alternator should be putting out a minimum of 13.50 volts. If not, it is not charging properly and needs to be replaced.
