My car has a manual transmission.

Hi there. It sounds like you have a failed alternator. The alternator is used to maintain the battery charge and provide electrical support to the electrical system. Its output can vary depending on the electrical load placed on the system; ac, blower motor, headlights, etc. Have the alternator tested at idle and under load to determine if the voltage/amps are not within specifications; replace as necessary. Also have the battery tested with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Replace the battery if needed. If the battery tests ok, then recharge the battery before starting the car with the new alternator. Not having a fully charged battery can present an undue load on the new alternator’s internal voltage regulator and shorten the life of the new alternator. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with an electrical problems inspection.
