Product Overview
The relay carries the higher current needed by the glow-plug circuit when the machine commands preheat. Failed internal contacts can leave the glow plugs without power and make cold starts difficult even when the glow plugs themselves test correctly.
The relay is used across multiple Hitachi EX and ZAXIS/ZX compact-excavator models. Match the 8942481610 number, case/support dimensions and terminal arrangement before installation.

Frequently Asked Questions
Q: How can I tell if the relay is the problem?
A: Check whether the relay receives a preheat command and whether battery voltage reaches the glow-plug output during the preheat cycle.
Q: Why match the mounting/support length?
A: Different relay cases can share similar terminals; the physical support and terminal layout need to fit the machine harness and bracket.
Fitment can vary by serial number, production date, engine configuration or prior repairs. Verify compatibility using the part numbers and application details listed above before ordering.
