Honda generator motor runs but no electricity.

Generators rely on a residual magnetic field to "kick start" the current making process. Yours has lost this field. Easy enough to fix however.
Plug in an electric drill while it's running. Squeeze the trigger and manually twist the end of the drill (this will act as a miniature generator, as the Honda has lost its magnetic permeability and this motor rotating in reverse will generate a small current and restore it). Take care as, as soon as you spin it fast enough to develop a current, the generator will pick up on this current and start generating it's own current; energizing the drill. Once the generator starts generating current, it will repair itself.

the generator is not big enough to run what you want
it needs to be 3500w minimum or 4.5w to be safe
although it is stated at 2500 watts , in fact that is the peak load on electric motor start up and its continuous rating will be around 1.8 watts
all of this is clearly stated on the specs plate on the generator

on the plate attached to the motor you will find several important items
one is the wattage of the motor
this is the maximum wattage that the motor uses when under load
the gen set will need to be at least 30% bigger than that figure
next there will the number of phases that the motor is
it will read as 1 ph or 3ph
If it is 1ph that is a single phase motor and will ru from a single phase gen set
however if it is 3ph you will need a 3ph gen set to run the motor
As most single phase motors are limited to around 5hp I would be very sure that the motor is not 3ph
specialist advice from an accredited electrician or electrical motor shop is recommended before buying a gen set. as if you need 3ph the gen sets become expensive.

If it has not been run in a while, the generator field may be weak and may need ot be flashed. Also make sure the motor is running up to full RPM.

Hope it works for you.

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.

you need an inverter generator. checkout the honda line.

Sorry, I don;t have a solution but do you have a good coil from one of those you would like to sell?
