Q: Electrical issue on 2000 Suzuki Esteem

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My Suzuki Esteem wagon has run into an electrical issue. I replaced the battery and it ended up getting drained. I replaced the alternator but it is not charging. Any other ideas to what part of the electrical system is acting up? It has about 123,00 miles.

Did you check ALL of your fuses, because there are a few that are vital to the Charging System? When I look at the wiring diagram for you Charging System on your Suzuki, I see that the Charge Indicator Light is in the Charging circuit ( typical ) so make SURE that that bulb comes on when you turn on your key and before you start the engine, then it should go out after you start the engine. If this does not work as I describe, then your Charging System will not Charge at all!
Another thing to be aware of is when you check your battery while the engine is running, it should read about 14.1 volts, if it does then the Charging System is working. If the Battery keeps going dead, it may be 2 other things, a parasitic drain, meaning that something electrical is not shutting off when you turn off the key, this will keep draining your battery while your car sits or you could have a defective battery. I just replaced a brand new battery in a car, that was 2 weeks old. Once in a great while, you get a brand new Battery that has a defect. If after all of thee checks, the Charging System will not work, maybe you better take your car to a shop and have a Pro Technician inspect the problem, you may have a wiring problem or even a defective new Alternator, yes I have seen that happen as well on more that 1 occasion.
