Bosch - 0332209151 - Relay Fendt Massey Ferguson

This relay controls the flow of current to high-draw circuits in the tractor's electrical system. It sits in the main power distribution box, switching loads such as the starter solenoid, fuel pump, or lighting circuits on and off based on a low-current signal from the control module. A failing relay typically causes intermittent operation or a complete loss of function in the controlled circuit. The 5-pin configuration provides both normally open and normally closed contacts, allowing the relay to either make or break a circuit depending on the control signal. The manufacturer's internal coil resistance and contact gap match the original assembly's switching characteristics, so the relay triggers at the correct voltage threshold without excessive arcing.
