You may not be able to rely on your battery and other electrical processes once your starter or alternator begins to fail. Bring your vehicle into Pep Boys if you experience any of the following.

Problem
Cause
Broken Gear
This condition is usually an indication of a bad fly wheel tooth condition or trying to start the vehicle while the engine is running. It can also indicate improper mounting or shimming of starter to mounting point.
Broken Nose Cone
A broken nose cone/mounting ears are an example of improper mounting, shimming and torquing in extreme conditions. It can also be also be caused by an engine backfire or an engine out of timing, or a faulty cam or crank sensor.
Burnt
The heat shield was not properly installed on the unit or was not installed at all, causing the heat of the engine to burn the starter. This is also evidence of bad connections and/or cables with excessive resistance, causing the unit to draw excessive power from the battery causing the unit to overheat.
Oil-Soaked
Visible signs of oil, grease or corrosion on the starter or solenoid are evidence of a leak in the vehicle. Oil, grease, or moisture can ruin intricate components like brushes, brush holders, contact points and armatures, and can start an engine fire. This leak should be addressed before installation
of replacement part.

Problem
Cause
Broken Mount
Broken mounting ears indicate that the mounting bolts were over-tightened or the unit was improperly mounted when installed, causing the housing to crack.
Burnt
The battery is not holding a charge of 12.4 or better; therefore, the alternator is continually charging, causing an overworked and overheated condition. This is also a condition of an alternator not putting out enough amps for the conduction needed to function.
Missing Pulley
During installation, a nut was not properly tightened, causing the pulley to fall off the unit. In many cases the installer/counter person will try to save a sale by swapping the pulleys. If performed incorrectly, the unit may be damaged. This is not recommended.
Oil-Soaked
Visible signs of oil, grease or corrosion on the alternator are evidence of a leak somewhere in the vehicle. Oil, grease, or moisture can ruin many intricate components including brushes, rectifiers and regulators. This leak should be addressed before installation of a replacement part.
Starters
When you turn on your ignition, the solenoid receives electricity from the car battery and then engages the starter with the flywheel. The starter turns the flywheel, which turns the engine crankshaft, which in turn starts the motions of a running engine.
AlternatorsProStart Products vs. Original Equipment >>Alternators
An alternator creates a current by spinning a magnet around at high speed, then running the current through a current rectifier. A rectifier changes alternating current (AC) into direct current (DC), enabling the alternator to produce power to run all the electronics in the car and charge the battery.
