My son drove in to town and the car was fine, he filled the up the jeep and after that it made a loud noise , would drive over 30mph. It was jumping and running really ruff. I took it to a mechanic, he said it needed a new alternator, battery, and serpintine belt. Replaced all, Still only registering 9volts, running really ruff. Light on says check guages, sounds bad, no over heating or anything.
What things can I check, since I replace all things? on 2000 Jeep Cherokee

Make sure he didn't put diesel fuel in it. Have somebody else (ask around for references) diagnose the electrical system!
