Hi Group I have a ACS keyed ignition switch with out starter contact for my Rotax 914.
I will be wiring as per Z16 where shields are grounded to engine near by the ignition
modules, then the shields are connected to the ground tab at the ignition switch.
To short the ignition wires to ground, path will be through the shields to ground at
the engine. The body case of the ACS ignition switch is not connected to the ground
tab where the shields will be connected.
My question: Rotax calls for the body case of the ignition switches to be grounded.
In my case do I need to ground the body case of ACS ignition switch? If the answer
is yes, can I ground it to the field of tabs on the cockpit side? Thx. Ron P.

I can deduce no reason in physics for doing this.
All of the ACS 'electrics' are 'floating' on
the rear, non-conductive closeout. The case
has no electrical function.
