Engine battery ground cable

[Pete Masterson]

Because it's cheaper. Ground straps don't need to be insulated, since they (and every other bit of bare metal) is a ground. The positive cables must be insulated so that they don't 'short' against a ground. Ground cables on batteries are usually (but not always) insulated since they pass close to the positive wires from the battery, and that avoids a chance of an inadvertent short.

Of course, if you use an insulated cable for a ground strap, it doesn't make any difference.

If it is a ground strap from frame to engine, you can use insulated 

cable. Best place would be a welder repair shop for no post cables . 

I never understood why many OEM's use bare braded cable for the 

ground?????
