I want to make sure I don't have electrical problems on 2005 Mazda Tribute

I think my alternator is bad but the pass headlight won't cut off. but nothing else at all can get power not even the door locks unless i hook a power source. it will cut off when your driving to. and then I could drive all the way home with my headlights on but if I turned the fog lights on it cuts off. The whole time it runs after you jump it all the lights dim constantly. any info would be greatly apreciated.

Sounds like a shorted wire in the circuit for the headlight. Wouldn't hurt to have alternator checked though. Wiring diagramwillbe needed to see what's powering the headlight constantly
