Alternator/Electrical?? SUV running fine, drove 35-45 mins and parked. Returned from shopping it wouldn't start. Seemed as though battery was dead so purchased a new battery. SUV started right up and drove 35-45 mins. home. Just 1/8 mile from home (country road & no street lights) noticed that headlights were dim. Drove into my driveway and shut the vehicle off. Guessing it might be the alternator, I tried to restart it and it wouldn't start. Next morning it started right up so I took it to my mechanic who ran it for 45 mins. and took it for a test drive thinking it may be shutting down once it got heated up. The alternator was charging perfect so he's at a loss as to what the problem is and suggests to drive it til .....I'm left stranded.....I guess! HELP???

I meant no start NOT no spark, even though my car developed a miss when my terminals were shot I meant no start NOT no spark, even though my car developed a miss when my terminals were shot

Hi Nick .....thanks for your input. The battery posts were cleaned and the ends as well. They were reattached very securely and the cables didn't seem to be loose at all but will have that re-checked! Thanks again Hi Nick .....thanks for your input.

Thank you......I'll get my mechanic to try this! Is this disconnection something that would happen all of a sudden as I had no problems prior to this? Thank you......I'll get my mechanic to try this!

Also....does this mean that the alternator is dying? Should I just replace it and be done with it? Thanks... Also....does this mean that the alternator is dying? Should I just replace it and be done with it? Thanks...
