Many of us supplement the standard ERA grounding because the fans, headlights, and taillights all take their ground from the frame. That means all electrons must either go through that one little black wire, or find their way back home via some other way, such as motor mounts, emergency brake cables, etc. What I have on my car is a supplementary 4 gauge wire that runs from the negative battery post to the chassis frame, and I run a grounding strap from the intake manifold to the firewall. I've taken umpteen amp readings on all of my electric circuits and that system works quite well. Many cars do it exactly that way, so it's not like I invented it.  |
Well my car is half right then. My POS MSD wire goes to the CB on the firewall like yours. My battery is in the trunk so my negative BAT cable goes to the frame in the back, so perhaps I should run my MSD neg wire all the way to the back to where the NEG BAT cable is connected to the frame, or directly to the battery. I guess I could also get a long NEG battery cable and run it to the front and connect it to where yours is connected.
As I said, MSD instructions and their tech dept want you to hook both wires directly to the BAT. I told them my set up and they said that was NG.
Last I talked with them was last year...I think I will call them again.
