If the diodes in the alternator regulator are shot it might still work with a low charge, but as soon you switch on lights and heater the tension goes down. Jeep runs like crap cause the fuel pump doesn't get enough current, and drains the battery. If you have a tester you can check the alternator by reading the volts on the batt terminals when engine is running and lights are on. If it's lower than 11 volts it's bad.

so first off last week one day my jeep died (i left my lights on) so my buddy helped me jump it he didnt know which cable went on which part of the battery and he ended up telling me the wrong sides so the cables started smoking etc. then we switched them and finally jumped my jeep.
