Mike...
On my 54 3100 6v I run 00 cable from battery hot to the starter and 00 from battery ground to the bellhousing. Then a regular automotive ground cable from the bellhousing to the frame and a lawn tractor ground cable from the frame to the cab.
Sounds like overkill but a 6v system lives and dies by its ground connections.
If you need the strap for authentic appearances then hide a good ground where it won't show.
Kind of like the old saying... You never have too much ammunition.
