No stupid questions, only stupid answers. Some were copper, some steel. Both usually flash plated with what ever was used to plate copper wire connectors.

Not the reason I have been told.


6V systems Another hint, what else was stated about 6V systems?



Not the reason, but you are right. Could be handy for jump starts.

So I did find three reasons with the right Google search. Now I know no one did that because the third reason is what I'm looking for. Maybe professional help: @Keith Seymore
I looked it up. Not sure what else you're looking for except static electricity, but I thought that was mentioned. Positive ground? High amp.

Ground straps are where I would pony up the money and get some nice braided straps.
Frame to engine block
Core support to frame
Cab to frame or engine block
Bed to frame

And of course a solid battery cable to frame.

Then double check all the smaller mounting grounds for the headlights and taillights.
Battery cable goes to engine . The starter and alternator are you're highest amperage circuits, so they get priority.

The braided design offers several key advantages for automotive applications:

  • Superior Flexibility and Durability: Because the engine sits on flexible rubber or hydraulic motor mounts, it constantly twists and shifts when accelerating or idling. A solid wire would quickly snap or suffer metal fatigue. The braided mesh flexes seamlessly with engine movement without breaking.

    • High-Frequency Interference (RFI) Reduction: Electrical components, such as the ignition system, continuously generate radio-frequency noise. Braided straps excel at absorbing and suppressing this electromagnetic interference (EMI) because high-frequency currents travel on the outer surface of a wire (known as the "skin effect"). The flat, braided surface provides a much larger overall area than a standard round wire, which helps safely dissipate this noise and prevents static over the car's speakers.

    • Voltage Stabilization: Properly grounded engine blocks and chassis ensure that all electronic modules receive a clean, stable return path for electricity. Poor grounding can cause "floating grounds," leading to confusing sensor readings, erratic transmission shifting, and heavy electrical load issues.

    • Heat Dissipation: The woven nature of the strap promotes better heat dissipation compared to enclosed, insulated wiring. This is vital near hot engine blocks, exhaust manifolds, or high-draw systems like the starter motor.

    • High Conductivity: Often made of bare or tinned copper, these uninsulated straps provide a direct, low-resistance path for the heavy electrical currents required to operate high-draw equipment and safeguard sensitive computer systems.

Number three on this list too. Heat dissipation. Also would help cool the battery after high use of amps after starting those engines running 6 volts.

I've said multiple times, used to be only cars with a factory radio got the braided ground strap from the engine to the firewall. No radio cars didn't get that ground. Now it makes more sense.
