Ranger engine ground

[danMichael]

'How is the engine supposed to be grounded to the airframe in an F24R?
On my aircraft, the starter is grounded to the engine case at the tach
drive housing, but the engine doesnt seem to be grounded to the airframe
other than incidental contact (e.g.: tach cable, throttle cable, etc.).
Was something removed? I plan on fabricating an appropriate solution,
but am curious how this was originally designed to work.

Thanks.
