RELAY - STARTER (CAT CT216G2-42321)

A failing starter relay can prevent the starter motor from engaging, leaving the equipment unable to crank. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT216G2-42321. The relay acts as an electrical switch that controls high-current flow to the starter solenoid. When the relay fails, the starter may not receive power, resulting in a no-crank condition. A stuck relay can also cause continuous starter operation, risking battery drain or starter damage. The item ships at approximately 0.18 pounds. Verify the serial number or application, then call (562) 693-7748.
