Multiquip 11965077910 Relay 3TNE88 - OEM Replacement Part for Trench Rollers

This relay controls critical solenoid and electrical functions in Multiquip trench roller systems equipped with 3TNE88 engines. In the RX1575 electrical system, relays manage the switching of high-amperage circuits including the starter motor, glow plugs, high-speed solenoid, hydro cooler fan, and various solenoid drivers. The RX1575 uses multiple relay types rated for 12VDC operation with varying amperage capacities (K1/K7 spec: 12VDC-40A/15A) to control everything from the starter relay (K2) and timer relay (K3) to the high-speed solenoid relay (K5) and glow plug relay (K6). These relays interface with the machine controller to manage engine ignition circuits, fuel shutoff solenoids, and hydraulic control solenoids for steering, drive, amplitude, and braking functions.

Failed relays can cause no-start conditions, loss of solenoid control, or intermittent electrical issues. The electrical system requires proper relay function for alternator output (14.5V at Term 30), ignition circuit power distribution, and ground-out signals to the display controller. Before commissioning or after electrical troubleshooting, verify all relay connections and test for proper voltage at control circuits.
