Hi all,
I have been given a generator to repair that is marked as Honda EU 2
Inverter 2000W, it has no 12 volt or AC output.
On opening the unit I see wires going from the alternator directly to
the output socket, I see no inverter?
Also I cannot see any slip rings or brushes.
Can anyone with experience of these please give me some advice on
how to trouble shoot?
Thanks in advance!!
Greg.

are the electronics installed in the alternator?

Many small alternators these days have a permanent magnet for a rotor
(as we now have magnets that are truely permanent). Ergo the
electricity is generated in the stator & there is no need for slip
rings or a rectifier to provide dc to create the magnet in the rotor.
So the device is much simplified. Assuming the insulation is intact
and there is electrical continuity/no short circuit in the stator
windings, it must work.
There may be thermal/ current overload trips/fuses also to checkout
The will be a means of regulating speed and voltage.
The speed control may be entirely mechanical and similar to what's
found on a lawn mower, ie a flap in the cooling air linked to the
carburretor/fuel injection.
The voltage control is the most likely culprit, these days likely to
be some sort of electronic gizmo!
Why would there be an inverter? It generates AC which is what's
required.

Clean consistant power and less fuel consumption I would guess. RPMs can reduce
when less power is demanded.

See page 16 of:

Looks like you need to reset some circuit breakers.
