Three Restoration Options for Your Failing Industrial Alternator

Posted on

The alternator is an important component in an industrial vehicle. In general, the alternator is designed to produce electrical current when the pertinent equipment is in operation. Some of the energy is stored in the battery and used to start the industrial vehicle. The rest of the power is used for running the electrical components in the vehicle. If the alternator fails, the vehicle will be forced to draw all the required power for operation from the installed battery.

As a result, the stored energy will be depleted fast, and your vehicle's electrical system will break down. Fortunately, you can prevent these detriments by recognising early signs of alternator damage such as dim lighting and charging light warning. The early detection will allow you to commission diagnosis and early refurbishment for optimal performance. Here are the main options for alternator repairs and restorations that you should consider for your industrial vehicle.

Simple Repair

The cheapest form of restoration for your alternator is simple repair. This is an ideal choice if the damage to the module is not extensive or severe. In general, this process involves identifying the internal components in the alternator which might have caused the failure. Moreover, the parts which are near failure due to extensive wear will also be replaced. Typically, this restoration option is effective as long as the faulty components are found. However, if the damage is not localised, this repair will only act as a temporary fix.

Rebuilding the Alternator

The rebuilding process is essentially similar to simple repair, but this procedure is more involved for better results. In general, the repair technician will start by dismantling the alternator and visually inspecting the internal components for signs of wear and damage. In addition, the electronic and electrical parts are tested using special equipment. Any faulty or worn components are replaced to restore functionality. In most cases, modules that have a short lifespan are replaced, regardless of their condition. The alternator will perform at great levels after reassembly and installation.


The most expensive restoration method for damaged alternators is complete remanufacture. It is also the most reliable way to ensure ideal functionality of the electrical system. Generally, the procedure involves dismantling the alternator and following strict guidelines on the replacement of internal components such as diodes, brushes and regulators. It is not normally economical to have your industrial alternator remanufactured. Therefore, you should purchase a remanufactured replacement alternator for the same or better results.
