Why is the voltage too high on my MarelliMotori M8B 315?
The voltage of your MarelliMotori Portable Generator may be too high due to: * Potentiometer V unset: Rotate the potentiometer until the voltage reaches the rated value. * Faulty regulator: Replace the AVR.
What to do if the voltage is lower than rated on my MarelliMotori M8B 315?
If the output voltage of your MarelliMotori Portable Generator is between 50% and 70% of the rated value, it could be due to several reasons: * Speed less than rated: Check the rpm (frequency). * Voltage potentiometer unset: Rotate the potentiometer until the voltage reaches the rated value. * Fuse blown: Replace the fuse with a spare. * Faulty regulator: Disconnect the AVR and replace it.
How to fix unstable voltage on my MarelliMotori M8B 315?
If you are experiencing unstable voltage with your MarelliMotori Portable Generator, the following could be the cause: * Diesel engine rpm variations: Check rpm uniformity and the diesel engine governor. * Stability potentiometer unset: Adjust the AVR’s stability potentiometer. * Faulty regulator: Replace the AVR.
What to do if my MarelliMotori M8B 315 alternator won't energize (no load voltage 20-30% of rated voltage. Voltage insensitive to AVR potentiometer's rotation)?
If your MarelliMotori Portable Generator's alternator isn't energizing and the no-load voltage is between 20-30% of the rated voltage, and the voltage doesn't respond to AVR potentiometer adjustments, consider these possible causes: * Fuse blown: Replace the fuse with the spare. If it blows again, check if the exciter stator is short-circuited. If everything is correct, replace the AVR. * Connection's cut on the exciter stator: Check the continuity and repair. * Incorrect connections of exciter stator: Reverse the two wires from the exciter stator.
