These are just the misconceptions the article talks about.
- chiph 8y agoI suggest you look at my list and read the article again. He is using ground loop isolators because of the length of his cable runs. In a car, that's not a problem as anything over 3 meters would be rare. Single point grounding makes sense, because as I said, steel is a worse conductor than copper, so you'll end up with a voltage difference between your grounds (from each to the battery) if you use more than one. So far as twisted pair, he strongly suggests using them to provide shielding against magnetic induced noise. They also provide good shielding against RFI - remember you've got 4-8 spark transmitters running at 900 to 5000 rpm interval in the engine. And using the same size wire for both power and ground makes sense because different gauge wire has difference resistance.
