Rely on tested quality and order glow plugs and glow time control units directly online.

Indispensable for cold starts

The glow system is essential for starting the engine in diesel vehicles: its components, such as glow plugs, ensure that the combustion chamber is sufficiently preheated. A suitable control unit regulates the glow time and ensures that the glow plugs are used efficiently.

Precision in control & fit

The glow plugs must have exact threads, lengths and electrical connections so that they function correctly and are firmly seated. The control unit must also be matched to the voltage, control functions and interfaces so that the entire system works reliably.

What should you look out for when buying:

GLOWING CANDLE

Make sure that the length, thread and connection match your motor exactly.

COMPATIBILITY

The glow time control unit must harmonize with the vehicle electrical system, the glow plugs and the control logic of your vehicle.

TENSION

Ensure that the components are designed for the on-board voltage (e.g. 12 V or 24 V) so that the glow system functions reliably.

Expert Guide: Everything You Need to Know About Generators and Their Parts

The generator (alternator) produces the electrical energy for the vehicle’s electrical system and charges the batteries during operation. It powers numerous electrical components—from the lighting and cab to the EBS/ABS braking system, AdBlue injection, and air conditioning—and is therefore essential for the vehicle’s reliable power supply.

An automotive alternator consists of many interrelated components: carbon brushes, field windings, rectifiers, a freewheel, mounts, fan blades, and a voltage regulator. Many of these components are available as individual replacement parts, allowing the alternator to be repaired as needed.

Trucks use a 24-volt architecture and require very high currents—often over 100 amps—to power their many electrical components. Components such as field windings and rectifiers must withstand these continuous loads and the high temperatures in the engine compartment without overheating or experiencing a drop in performance.

Typical signs include a lit charging indicator light, weak or dead batteries, flickering lights, unusual noises coming from the alternator, and electrical system failures. Common causes include worn carbon brushes and slip rings, defective rectifiers, or a faulty voltage regulator.

The voltage regulator maintains a constant charging voltage, thereby protecting the batteries from overcharging and undercharging. In a 24-volt electrical system, it must be precisely calibrated to the typical charging voltage of approximately 28 volts. A faulty regulator can quickly lead to battery damage or an insufficient power supply to the electrical system.

The replacement part must be precisely matched to your generator model to ensure that the threads, dimensions, and connection layout are compatible. Make sure that components such as the field winding or rectifier are rated for the voltage and current (24 V) and are corrosion-resistant, as they are exposed to dirt, moisture, and road salt.

We carry replacement parts and accessories for trucks, trailers, buses, vans, and agricultural vehicles—including both premium brands and compatible OEM and aftermarket parts as cost-effective alternatives. This means you can find the right solution for nearly every common commercial vehicle.
