inverter generator ignition fault

[sardine]

Got a Kipor copy of a Honda EU 2000, with no spark, I've got a new ignition module on it and every other ignition component tests the correct ohms. The plug is good, so i think its either the ignition power winding is weak, or the ignition trigger pulse is too weak. The bump on the flywheel rotor that triggers the ignition has no magnetism , ie a screwdriver won't stick to it, is this normal ?

I don't know what voltage readings I should be getting from the trigger and ignition power windings when I pull start it. Maybe I could rig up an alternative bench power source to bypass the ignition power winding ?

This is my battered old work generator, and not worth spending big money on, I just want to keep it going until the inverter board blows.

Check the gap between the flywheel and Coil pack, Aprox. 25 to 32thou is enough.
Make sure the surface of the magnet is clean.
Make sure the coil pack is bolted to clean metal.
There may be 1 or 2 thin leads heading to cut out, check them.
Check the Cut out. on of switch has not gone mummery glands vertical.
The spark plug can have a wide gap and get dirty, egg sucking time I know.


The coil magnet on the one I fixed early this year had a weak field, but when it was cleaned up an a diffeant bit of test steel was used it improved.

The green ignition power winding wire dissapears into the inverter board, there is no continuity between both ends of this wire, anyone know what It could be connected to in there ?

Has the wire on the stop switch chafed through to ground somewhere?

The wire into the inverter board could be engine shut down, are you over thinking this ? Is it just a simple coil ignition bolted next to the fly wheel ? If so they usually have one wire which when grounded cuts the ignition, if this is same as yours disconnect wire from coil and check for spark again, some have safety cut outs like low engine oil and overheat sensirs

Its a CDI ignition, the ignition switch and low oil sensor are both OK, the system runs on 27 v ac to charge the capacitor so the manual says.

And what's that yellow block on the PCB, a ferrite ?

 

[Jim Davey]

Yep, certainly looks like it.

 

[the snooper]

is that capacitor damaged far right ?

 

[xmetal]

is that capacitor damaged far right ?

I thought that too. It looks like something has been having a nibble of the components in that area.

I thought it may have burst

 

[sardine]

Yep that cap is knackered.

Hi chap interested to learn if you had any luck with your gennie? I thought Id have a go at repairing a spares repair one. Did you replace the capacitor? Id have thought it reasonable to fit one to the tails as they emerge from the resin
