RECOMMENDED SOLUTIONS
1. Check the circuit breakers or the circuit breaker of the main and bypass circuits.
2. Check the connector block connections, as you did in step # 4 of the installation
process. ATTENTION: Make sure that the main supply of

The following measures should be sufficient to eliminate much of the vibrations:
Check the level of vibrations after each step.
1. Check that all blades are properly screwed to their supports.
2. Check that all brackets are securely attached to the engine.
