The Electrical Parts parts that fit the most machine models.

Parts of the electrical system

On construction equipment the electrical system covers starting, charging, sensors and lighting. Here you will find alternators, starter motors, speed sensor and oil pressure sensor groups, pressure switches, and signal and work lamps.

  • Alternator and starter: charging and cranking
  • Sensors and switches: feed engine and hydraulic data to the controller
  • Lamps: lighting and signaling

These products come from CTP, which makes OEM-quality parts for Caterpillar and Komatsu machines. Volka Makina is the authorized regional distributor of CTP.

Finding the right part

For electrical parts, voltage, connector type and mounting must match. Search the part number, or use the Part finder with the machine model and serial number. To ask about many items at once, use Paste a parts list.

For starting or charging problems, first check battery terminals, cable connections and the ground path; a poor connection often looks like a failed part. When replacing a sensor, inspect the connector and wiring as well to prevent a repeat failure.

Frequently asked questions

What should I check first if the starter does not crank?

Battery voltage, terminals and the ground connection. If those are fine, inspect the starter motor or solenoid.

What if the alternator is not charging?

Check belt tension and cable connections; if the problem persists, the alternator should be tested.

The warning light stays on after a sensor swap. Why?

Check connector and wiring damage, and send us the fault code if needed.
