Solenoid Relay for Honda GX Engines
This 12 V DC starter solenoid relay fits Honda GX240, GX270, GX340 and GX390 engines rated from 8 HP to 13 HP. It supports generator models EC5500 and EC6500 as well as water-pump applications. The normally open contactor assembly replaces the original starter contactor on these small-engine power units.
Normally Open Copper Contacts at 12 V DC
The relay uses copper-alloy contacts in a normally open configuration rated for 12 V DC motor starting. DIN rail mounting and a choice of solder, screw or quick-connect terminals simplify wiring in the field. No fan, radiator or active cooling is present, so operation is silent and power draw is limited to the coil current during cranking.
Single Contactor Assembly in the Box
The package includes one starter contactor assembly solenoid with no additional brackets, harnesses or software. Installers must supply mounting hardware and wiring suited to their terminal choice. Buyers needing a complete wiring kit or a dual-solenoid setup for redundant starting will need to source those parts separately.

Questions about this item
How do I install the 12 V DC solenoid relay on a GX390 engine, and what wiring step is often missed?
Mount the relay on a DIN rail or flat surface, then connect the battery positive to the large input terminal, the starter motor to the large output terminal, and the ignition switch to the small control terminal; the step often missed is securing a clean chassis ground for the coil circuit.
What maintenance or replacement will the copper-alloy contacts need after extended cranking cycles?
The normally-open copper-alloy contacts can develop carbon buildup or pitting; inspect them annually and replace the relay if voltage drop across the closed contacts exceeds a few hundred millivolts during cranking.
What limit appears first when the solenoid is used for repeated hot restarts on a 13 HP generator?
Coil heating from successive 12 V DC activations raises internal resistance, slowing pull-in speed and eventually preventing reliable engagement until the relay cools.
