SM with OBC issues

[OneLapper]

It's been a while since I've posted

I'm working on a SM that will not charge.
When you plug an extension cord into it, the OBC does not see any voltage
When you plug it into my EU Honda generator, the OBC doesn't see voltage
When I bond neutral and earth on the generator, it prompts you start the charge cycle but immediately faults on with "STOPPED 121 - GFCI test failure"

I haven't seen the GFCI test failure fault on a SM Wondering if it's in the OBC or A pack BCU.

Looking for advice or a replacement OBC if that's what it needs

Thanks,

Mark

Nice to see you back! Does it work without an extension cord? Is the switch on the cgfi working correctly on the charger? Is it possible some of the wires have come out?
