nother day nother problem (Page 3/3) cartercarbaficionado MAY 02, 09:41 AM quote Originally posted by theogre: [QUOTE]Originally posted by olejoedad: It is a relatively common practice with the 2.8's to add another ground wire from the engine block to the chassis. I read about this years ago on this Forum and pooh-poohed the idea. When I finally did do it, the engine ran better and idled better. Just a thought. Just means Other Two Grounds from Block to Frame had problems & adding more wires can cause other problems because can make Ground Loops that causes big problems w/ ECM ICM etc. Factory Installed... 1. Main Ground is often braided "strap" that can be replace/upgraded easy. Quick Example: www.dormanproducts.com/p-28495-60213.aspx 2. Secondary Ground just a big wire often attach between trans bell bolt & frame. Either or very likely both have crap/rusty ends often bolted to the frame anywhere easy for factory worker to quickly screw w/ power tools. Braided Grounds caries more Amps than similar normal wires. Don't replace that w/ normal wire. OEM Battery Cables did not have small ground from Battery to Frame but many add it later when getting new ones. Even this can cause Ground Loops when the others above are Iffy. clean/fix see https://web.archive.org/web...ierocave/ecmwire.htm[/QUOTE] question. where does original ground run to on a stock v6? I'm beginning to suspect it's been caught and torn off olejoedad MAY 02, 04:33 PM The main ground to the chassis is the heavy braid from the front passenger head to the passenger hinge box. The ground to the ECU is through the C500 and also directly to the ECU. The ground to the battery is to the front head, passenger side. cartercarbaficionado MAY 02, 05:10 PM quote Originally posted by olejoedad: The main ground to the chassis is the heavy braid from the front passenger head to the passenger hinge box.
