THE AVR module has likely failed. It regulates the voltage as load is increased.

This ASSUMES the motor is running solidly and doesn't slow preceptively.

The voltage is regulated by a Regulator... and produced by a rotor/stator.

You will first need to check the voltage before and after the regulator to determine where the problem lies.

Professional help is recommended for this type of electrical servicing.

Thanks!!

Honda ems 4000 generator starts and runs great, but no power


The plunger is stuck where the governor rod which is spring attached to the frame is. If you locate the governor metal rod on the lower level of the unit. zrock it to a higher rpm as you would a car carburator from under the hood.
This will free the plunger and the green light will go on and your current meter will register 120 volts.

When you lay up the generator for quite some time it often sticks closed. With monthly start up you will no have this problem reoccurr.

Honda ems 4000 generator starts and runs great, but no power


At the controller, you need to see if it is actually sending electricity out of the Generator/Alternator, have a look where the leads from the power making unit mates, (Think of it as a motor in reverse) onto the board. There should be an AC Voltage there, then, work back, or out from there, trace the Voltage until it stops, thats the problem... Check the Breaker isn't tripped or faulty too.

this is normal, do not worry that harmonic vibration type noise just tells me that the unit has a full freon charge and is running great, sit back and enjoy

New Onan 4000 watt gas RV generator cuts out


The generator engine is jetted for sea level. When you run at 24 hundred feet, it's flooding out. That's what you smell. The carb will need to be jetted for high altitude.

Hi, The 4000 rv unit unit is equipped with full diagnostics, and is indicated by the status light blinking. The blinking sequence, blinks a code as to the fault. If your unit runs and the status light is on without blinking, it is either the circuit breaker on the genset or in your distribution panel that needs to be reset. Good Luck, this should Fixya!
