Some faults with the electrical system can have misleading symptoms; what may seem like a faulty starter or alternator could be caused by a problem with the battery, a bad earth cable or even the engine management system. A common fault on older cars is when a voltage-sensing alternator is fitted and there is no 12 volt supply to the unit (for example if your battery is already flat) then the unit will not produce a charging current. This is not a fault, it is done by design. If in any doubt about the electrics on your vehicle then please consult an experienced, qualified auto electrician. Quite often we find that normal mechanics are unable to diagnose some of these electrical problems successfully.

Where there are a nunber of alternate parts listed for your car (particularly where there are differing power outputs) these units are not always interchangeable.
