Default Ignition switch center ground

Hi Guys,

I'm wiring in my ACS A-510-2 ignition switch and the wiring diagram shows the center ground wired to the nearest structural member, but bob from AeroElectic states that , "p-lead shields should
be grounded to the airframe/engine only at the engine end. The
shield is used to provide a ground for the "GRD" terminals at
the switch but no other connection to the shields should be
made at the instrument panel end". Should or shouldn't I ground at the switch?

Cheers
Gibbo

You can do it either way, but I run that terminal to airframe ground. I do not connect the plead shield there. That wire is used to ground the pleads when the switch is either off or in the single mag position (grounding in this case just the other mag).

Thanks Jesse, do you ground the shielding at the engine end?
