This FOXSTAR unit replaces part numbers 307-2570, 307-1617 and 307-0845 and is built to deliver the high-current switching needed to engage your generator's starter motor. It combines corrosion-resistant copper internals with a flame-retardant ABS housing so it stands up to vibration, heat and typical RV service environments.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this relay restore starter performance?\u003c\/h3\u003e\n\u003cp\u003eThe solenoid acts as an electromagnetic gateway between the battery and starter motor, enabling a large current flow only when the ignition circuit calls for it. Replacing a worn or failed solenoid with this FOXSTAR unit returns reliable engagement and consistent starting behavior.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirectly replaces 307-2570, 307-1617, 307-0845 and equivalent part numbers.\u003c\/li\u003e\n  \u003cli\u003eCopper windings and contacts for strong conductivity and minimal voltage drop.\u003c\/li\u003e\n  \u003cli\u003eQuick plug-and-play swap with the original mounting and terminal layout.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction extend its service life?\u003c\/h3\u003e\n\u003cp\u003eThe relay uses an ABS plastic enclosure rated for high insulation and flame resistance, while internal copper components resist oxidation and maintain stable conductivity under load. This construction helps it tolerate exposure to oil, dust, and temperature swings common in RV generator compartments.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFlame-retardant ABS housing reduces heat-related risks.\u003c\/li\u003e\n  \u003cli\u003eAnti-oxidizing copper coil and contacts for long-term electrical stability.\u003c\/li\u003e\n  \u003cli\u003eRobust build designed for vibration resistance in vehicle-mounted use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is installation and compatibility with my generator?\u003c\/h3\u003e\n\u003cp\u003eInstallation is intended to be straightforward: remove the old solenoid, position the replacement, and reconnect the terminals. Because this part is engineered to match the common Cummins Onan relay geometry and terminal layout, it fits many RV generator models that used the original part numbers.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with Cummins Onan RV generators using listed part numbers.\u003c\/li\u003e\n  \u003cli\u003eSame terminal configuration for a simple swap—no special tools required beyond basic hand tools.\u003c\/li\u003e\n  \u003cli\u003ePlug-and-play fit minimizes downtime during repairs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat practical checks should I do after installing the solenoid?\u003c\/h3\u003e\n\u003cp\u003eAfter fitting the FOXSTAR relay, verify firm terminal connections and test starter operation under normal conditions.
