Electrical Electronic Spare Parts

A no-start in the yard usually traces back to one of a handful of components: a dead alternator, a worn starter, a corroded relay, or a sensor feeding bad data to the ECU. The electrical and electronic category pulls those together — charging and starting units, engine and machine sensors, wiring harnesses, control modules, dash monitors, switches, relays, and solenoids that actuate everything from fuel shutoff to hydraulic pilots. On modern construction and mining equipment, an intermittent sensor or a chafed harness can throw fault codes that mimic a major failure, which makes pulling the correct part the difference between a quick fix and a wasted afternoon.

Because part numbers on electronics shift often across model years, our specialists match components by OEM reference, serial number, or the number stamped on the old unit, checking against a 564,000+ cross-reference database. We carry 100% OEM components for 75+ brands. Free worldwide shipping applies to any country, and most electrical parts leave the warehouse inside 1–2 days and land in 5–7 days with tracking, so a downed machine does not sit waiting on a relay.

Frequently Asked Questions

What Electrical and Electronic Parts Can I Source Here?

We supply alternators, starters, sensors, ECUs, wiring harnesses, and operator monitors for construction, mining, and industrial machines. Coverage spans 100% OEM options across 75+ brands. If you have a fault code or a failed component, our specialists cross-reference it against 564,000+ part numbers to find the correct replacement.

My Machine Won't Start — How Do I Know Which Part to Order?

A no-start can trace to the battery, starter, alternator, a bad ground, or an ECU input, so pin down the symptom before ordering. Give us the fault code shown on the monitor plus the machine serial number, and our parts specialists identify whether you need a starter, sensor, harness, or control unit.

Are ECUs and Sensors Interchangeable Between Machine Models?

Often not. ECUs carry model-specific calibration, and sensors vary by thread, connector, and signal range, so a physically similar part may not function. Confirm fitment using the OEM reference or the number printed on the existing unit. Send us that detail and we verify electrical compatibility before the part is dispatched.
