Battery light stays on

1987 Honda prelude keeps draining batteries. Replaced the battery thinking it was the cold weather, still wouldn't charge. Changed the alternator, because the internal regulator was burnt out, and the battery still wont hold a charge.
Has this happend to anyone else and they can help? Please and thank you!

sounds like you either have a drain, or got a faulty alternator. if you decide to change alternators again, make sure the battery is good or it could cause a premature alternator failure.
