Quote: Cab... are you asking which way CURRENT flows out of a battery, or which way ELECTRON's flow out of a a battery. They are equal but opposite in answer...
As for the ground disucsion... I think many people believe going through the chassis is a bad way to ground because they've had trouble with the interface between the wire and the chassis. Corroded wire to chassis will obviously cause an issue. But that is no fault of the chassis as a ground, that is just a poor connection (which can happen with direct wire also). The chassis ability to carry the ground is perfectly fine as long as you do a good job connecting the wire to the chassis.
If current won't flow through a welded steel part, you have some serious issues with the weld quality... lol
ok will current flow through a piece of steel or a copper wire better?
