Hey guys,I have access to 6 ga copper wire. Could that be used for engine grounds also for body to frame.
1956 f100 292 you block out of 63 f100

 

That would be fine, but where does your battery ground cable go? It should go to the engine block. So it would be better to go from the block to the cab, and block to frame.

 

AWG 4 copper stranded would be preferred. AWG 2 welding cable would be perfect because of it's flexibility.

 

I assume he's not asking about the main battery cable, just the grounds from the block to frame and cab. 35 amps doesn't need more than #10 at most.

Or is this 6v? Even so...

 

On my truck the OEM flat braided strap from chassis to cab and engine to chassis is just slightly smaller (I think)than an uninsulated battery ground strap. Maybe they just did this for inventory reasons? It's probably good for 100+ amps.

 

Yes just the straps from block to frame and cab to block...it's 12v and thanks for the repys

 

Good source of ground straps.

Mixer Man nailed it. Flat braided is the way to go. The more the better.

Even if he's getting #6 for free?

 

I think the flat braided may also help with static spikes if he has a radio. Yeah, it's really hard to beat free, but personally I would opt for the flat braid, even over the welding cable, for it's flexibility and ease of installation. Unless it's too too pricey.

 

I found a 19" braided cable at custombatterycable.com. They come in 2 and 4 gauge and in 7,9,11,14,16,19,24 and 27 inch lengths.
