Heavy Equipment Electrical Parts and Replacement Components

Explore heavy equipment electrical parts at Fab Heavy Parts for construction machinery, aerial lifts, diesel engines, and other equipment applications. This electrical parts collection includes replacement control boxes, electrical connector kits, sensors, electronic control components, and selected engine electrical parts.

Electrical components perform different functions, from transmitting control signals to connecting wiring and monitoring equipment operation. Identifying the correct replacement requires attention to part numbers, equipment configurations, and electrical specifications.

Control Boxes and Electronic Control Components

Our selection includes replacement control boxes, joystick control assemblies, and electronic circuit boards for selected aerial lifts and construction equipment.

Examples include control boxes listed for Skyjack SJIII 3215, 3219, and 3220 scissor lifts, as well as Genie GS-series and GR-series machines. The electrical parts collection also includes ALC500 ECM circuit boards for selected Genie boom lift applications.

These components differ in their intended equipment applications, connector arrangements, and control configurations. Browse our aerial lift parts for additional application-specific replacement components.

Electrical Connectors, Sensors, and Engine Controls

Find electrical connector kits, including Deutsch DT connector assortments and selected kits supplied with crimping or removal tools.

Available connector options differ in terminal sizes, contact types, connector configurations, and included accessories. Matching these details is important when repairing or replacing electrical connections.

Our electrical parts collection also includes speed sensors, throttle position sensors, and throttle motors for selected Caterpillar equipment and engine applications.

Damaged wiring and connectors can contribute to intermittent electrical faults. Our guide to wiring harnesses for heavy equipment explains common wiring problems and considerations when inspecting electrical connections.

Choosing Electrical Replacement Parts for Your Equipment

Before ordering, check your equipment manufacturer, model, serial number, and existing component part number.

For control boxes and electronic modules, verify the listed equipment application and connector configuration. For sensors and electrical actuators, compare the specified voltage, electrical connections, and mounting details where applicable.

When selecting connector kits, review the terminal type, wire-size compatibility, and included tools or accessories.

Use the individual product descriptions to confirm the replacement component intended for your equipment rather than assuming that similar-looking electrical parts are interchangeable.

Frequently Asked Questions

How do I find the right electrical replacement part for my equipment?

Start with your equipment manufacturer, model, serial number, and the part number on your existing component. Compare these details with our electrical replacement part listings. Depending on the electrical part, you may also need to verify voltage, connector configuration, mounting points, and other specifications. Similar-looking components are not necessarily interchangeable.

Can I replace my control box with one that looks similar?

We recommend confirming the part number and equipment application before choosing a replacement control box. Different versions may have different connectors, control functions, or equipment requirements, even when their housings look similar. Check the listed compatibility and relevant electrical details rather than relying on appearance alone.

What should I check when choosing an electrical connector kit?

Check the connector series, number of pins, terminal type, and supported wire sizes. Some kits include crimping or terminal-removal tools, while others contain connectors and contacts only. Compare the kit contents with your repair requirements before ordering, and verify that the components match your existing wiring connections.

What should I inspect before installing a replacement sensor or electrical component?

Compare the received component with your original part and the electrical replacement part listing. Check its part number, connector shape, mounting arrangement, and specified electrical requirements. Inspect the existing wiring and connectors for visible damage or corrosion. Follow the equipment manufacturer's service instructions for the appropriate installation and testing procedures.

Why does my equipment still have electrical problems after replacing a component?

The original fault may involve another part of the electrical system. Damaged wiring, loose connectors, poor grounding, or power supply problems can sometimes produce symptoms similar to those of a failed sensor or control component. Verify the replacement part's application and have the relevant circuit diagnosed using the appropriate equipment service information before replacing additional parts.
