So I’m thinking I had a bad connection at the engine battery and lost power so just the alternator was giving power then I beeped my large horns when driving everything shut off. I think I need a new alternator now?

The only way I could start the motor was to push the auxiliary battery switch. The batteries are good but the house battery disconnect switch above front door does not work. Any help would be great.
