AlternatorAltenator
The alternator generates direct current for recharging the battery and also powers vehicle electrical loads.


Maintenance and Care:
It is a good idea to have your car, truck or SUVs entire starting system tested periodically. This will determine if your car's alternator is putting out the correct amount of current and voltage. A problem alternator could cause a battery to discharge, improper operation of lights and/or accessories, even erratic engine operation. Your local AAMCO center can provide you with a comprehensive starting, charging and battery test.

Battery
Batteries are the backbone of the electrical system and work the hardest in cold weather. If you live in an exceptionally cold climate, you may want to consider upgrading to the largest capacity available for your vehicle.

Maintenance and Care:
Make sure the battery is securely mounted because vibrations can have an impact on the battery’s performance and life. The battery and connections should be checked at every oil change (and are inspected as part of AAMCO's ProtectCheck). Unlike other components in your car or truck, the battery does not give warning signs when it is near failure. However, if it is hard to start, or you experience a delay after turning the key in the ignition, have your battery checked as soon as possible. Please refer to your owner’s manual for factory recommended maintenance intervals for your specific vehicle. Your local AAMCO center can provide you with a comprehensive starting, charging and battery test.

Lighting, Fuses, Circuits, Switches & Starter
Cars have a variety of lights: headlights, parking lights, brake lights, turn signals, dome lights, and more. Lights are a critical safety component in your vehicle and you should be alert for any malfunctions. Fuses, circuits and switches also control many other functions in today's vehicle, from power seats to power windows to just about any accessory or feature in the vehicle.

Maintenance and Care:
The operation of your critical exterior lights should be checked at every oil change (and are inspected as part of AAMCO's ProtectCheck). Potential causes include bad bulbs, switches, and fuses. Your AAMCO center can assist you with any malfunctions in your lighting system and replacement of circuits, fuses and switches.
