my 93 prelude was doing the exact same thing and for me it was my alternator was working properly.
go to a parts store and have them test it.

either your alternator has gone or your fan belt is not there which helps the alternator to charge the battery get a volt meter on your alternator to see if it is kicking out what it should be

either have a shop scan it for trouble codes or buy a scanner your self at local parts store have OBDII scanner and find out for your self it could be a number of things.

Have you checked the alternator fuse? The regulator needs power from the fuse to turn on the alternator. The old alternator could have blown the fuse.

the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck
