תרגום - אנגלית-עברית - Does not have power on heart of volunteer

I think the source here is faulty. Is it?

Thanks for the note milkman!
Yes, I set it in "meaning only" as requester is not a native speaker. This text is trunked there's no subject moreover, it is understandable though, that's why I didn't remove it.

Can you please re-phrase it for me if you understand it?

[it] hasn't got any power on a volunteer's heart
(or "it hasn't got any power on a good willing heart)

Oh! I see.
I got that completely wrong.
Thanks!!
