My Dear Steve
Some systems already give false triggering, like the backup generator supposed to start when batteries get low, it starts at random ocassionally, my analysis is that the gnd body keeps the noise inside the vehicle and pumps it to other systems via gnd. I guess this blows the idea of solid gnd plane.
My understanding is having the body of the vehicle and all other systems isolated from gnd, all signals input and output isolated optically. power supply lines are heavily filtered with EMC components.
Does anybody have an idea that can be taken as evidence accepted in court!
thanks
