on the back upper passenger side of the block is a 3/8 ths blind threaded hole about 1" deep. I think it is ideal for a ground and probably intended to be used for a ground.
I just picked up a length of negative battery cable to add for my chassis ground. I wonder if the braided ground straps offer any advantage?
I'll have to study on this before relocating my battery to the trunk.
Jeff,
They really don't. I spoke with my father about this who is an Electrical Engineer with 35+ years experience in DC Power. I asked him about using 0 Gauge wire versus say 16 gauge wire, or braided wire straps. He said there's really no difference between all of them. The amount of actual power that you're flowing through most ground straps is so minuscule that the gauge of the wire isn't the factor, it's more about providing a short and effective path that is important.
He added several extra ground points to his Scion Xa, as it was a popular and simple mod to do, but instead of using the HUGE 0 gauge wire that people were recommending (Because many people perceive bigger as better, because it can "flow" more) he used some 18 gauge wire that he had laying around our garage. And based on readings off an Ohm Meter, he was seeing the same positive effects the guys with the huge wire were seeing.
What you really want to make sure is that you have a quality connection to the metal, and that the cable is rather well sealed from corrosion intrusion. Corrosion and Oxygen equate to a higher resistance in the wire, and that limits its ability to flow current.
