Well first of all if you jumpstart a vehicle with a low charged battery you can cause an overload in the alternator regulator. Hence burn up the alternator. Charge the battery fully and have the alternator checked to make sure it is putting out 14.5 amps. If putting out more on a fully charged battery then you have a shorted circuit.
