I agree with the above; however it depends on which bit of the
airframe the grounds of all the loads are returned to.

I fly a Socata TB20 and on that, everything is grounded to a common
point, close to the firewall. So there are no currents of any
significance flowing through the "passenger" ****tion of the airframe.
