If you get into your Cadillac in the morning, turn the key and nothing happens, it could be a couple of things. If the battery has a good charge and the wires seem to be in good condition, you may have just found that you have a bad Cadillac starter. This device is a large electric motor that supplies the engine with the initial power it needs to start running. Within the case of the Cadillac starter is a set of large magnets, which surround a separate inner core. The inner core is a piece of iron that is wrapped in copper wire, and it is free to spin. When power is supplied to the Cadillac starter, the power enters the body and is transferred to the inner core by small metal springs called brushes. The inner core than becomes an electromagnet, and it reacts with the permanent magnets in the case to create a spinning motion. When the Cadillac starter fails, the most common reason is that the brushes have worn so much from friction that they can no longer transfer power to the inner core. Another common cause of a failure is that the teeth in the pinion gear have worn. The pinion gear of the Cadillac starter directly transfers the power to the flywheel, and, thus, the engine.
