Why won't my car start or take a charge?

I would say that your battery is the source of the concern first and foremost. Have your battery checked professionally and see if it is indeed faulty. If so, replacing your battery may solve all the concerns you are experiencing. Once a known good battery has been installed, you can check for other electrical system functionality.

Many fully automatic battery chargers will NOT charge an extremely discharged battery.. Try jump starting - and of course have battery tested - as described.. ⚠️ Severely corroded battery cable connections can cause these symptoms as well.
