Alternators and Parts |
| Alternators often fail from age and misuse. Disconnecting the battery when the car is running can cause loads on the diodes that will cause premature failures. Overzealous charging of the battery can also cause diode failure. Replace your alternator with one of our good quality Rebuilt units. The rebuilt units have new bearings, new windings, and also new diodes. Check the alternator in your car prior to ordering your replacement.

Voltage Regulators  |
| Electricity flows in the same way water does, if you put a funnel under a flowing source of water, only a certain amount will be able to get through at a time. Voltage regulators work in the same way. They keep the voltage in your car flowing at a constant, controlled rate. Over time, age and normal driving conditions can cause voltage regulators to fail, causing over or undercharging of your BMW's electrical system. Replace your voltage regulator today and keep your BMW's electrical system in check. |
