AGCO - LA340480297 - Starter Relay 70A Massey Ferguson

This starter relay is a 70-amp, 12-volt component that controls the high-current circuit for the engine starter motor in a grain harvester. It sits in the electrical system between the ignition switch and the starter solenoid, acting as an intermediary that allows a low-current signal from the key switch to close the high-current contacts that energize the starter. A failing relay typically produces a clicking sound without cranking, or intermittent starting behavior, as the internal contacts become pitted or corroded. As an original AGCO part, the relay is built to the same contact-gap and coil-resistance specifications as the assembly it replaces, ensuring consistent engagement timing and current draw. When installing, verify the mounting orientation and that the terminal connections are clean and tight.
