When your Nissan cannot start on a cold morning, it may not necessarily be the fault of the battery. The fault also may lie in the Nissan alternator. As the vehicle ages, the small pieces of metal that transfer the current from the moving portion of the Nissan alternator will begin to wear as well. When these devices, known as brushes, fail, the alternator may still continue to operate, because it is actually a set of three separate power generation circuits. The power that the Nissan alternator produces will be reduced to a certain extent, however. This means that the electronics in the vehicle will still receive power while the engine is running, but the battery may not receive enough power to be fully recharged. Extra demand is now placed on the remaining circuits, and this will hasten the complete demise of the Nissan alternator.
