Nowhere, it's safe, again. We use to see this problem all the time,
where GM accessories were cooked when the type of battery cables (four connections) they used in the fifties would disconnect the their smaller leads.

I think of all the body ground straps I have seen go bad on Jeeps so things like the headlights 'could' pull a chassis ground to the CB then to the negative lead to the battery. Even the starter could pull the other way through the body ground strap and back through the transmitters negative, if the big ground goes bad at the block which I have 'also' seen happen on Jeeps more than once.
