To recap slightly. I have zero dc voltage coming from the stator.
What are the likely causes for this?

hi Bob

with the engine running:

1. with the field wires connected to the rectifier, check the voltage at x and xx, and note the voltage.

4.5mv dc

2. remove the two field wires from x and xx and apply 24 volts, and then check the 3 phases to see what power output you get, and note the voltage

15.7 v ac on 3 phases

3. with the two wires removed, and with them connected to 24 volts, check the output on the two x and xx posts of the rectifier, note the voltage.

177 v dc

4. with the two wires removed from x and xx, and connected to 24volt, check the voltage on each of the input posts of the rectifier, note the voltage.

287.7 v ac across 3 phases.

Hopefully some good data there?

When I disconnect the field wires from the rectifier, x and xx, run the engine I get 0 vdc from them

can you check the voltage on the field wires while the generator is running, check to make sure you have voltage there and let me know what it shows..

The field wires? Is this between x and xx  and should they still be connected to the rectifier or disconnected?

Hi Bob
When flashing x and xx should they be disconnected from the rectifier?

Hi Bob
Have tidied up the wiring and fitted bridge rectifier.
When run i only get 16.35 volts on all 3 phases at the head.
I have flashed the stator field with 24 dc. Done this twice now in accordance with manual.
Engine running at a constant 1570 rpm.
Any pointers as to where the problem may be?

Thanks Bob
Will digest this and hopefully make some progress.
I’ll update the post as I progress.
