Grounding motor or TB.

I'm part of a Dodge Forum because I have a Ram and I seen on there that they were grounding their TB's and motors with 4 gauge wire and getting a better throttle response and a smoother idle out of it. Anyone on here try or hear of this?

I have never done this for good throttle response but for electrical integrity yes this should be standard methodology for a good running system; heavy gauge grounds, bare metal connections and protection of the connections.

When you think on it the only ground for the engine is the negative cable from the engine head to the frame, with a lot of dirt and $hit buildup from the road and trail, and the grounds are hunting for a path to get back to the battery (actually to run from the battery).

Adding ground wires from the alternator to the frame and a good HD ground wire from the engine to the frame and then to the battery is a great idea and it will not only reduce resistance in the ground path but should increase the output of the alternator and make sure the full current/voltage is running in the systems.

Another thing to do is add a ground wire from the negative post of the battery or a ground stud close to the battery to one of the starter bolts, this too allow full current flow to and from the starter allowing the starter to run at full power without working its @ss off.

If you are drive by wire then I can see upping the ground helping, otherwise I doubt it will do anything on a cable driven tb.

Thats because most Dodges have a horrible ground system. Our Diesels at work will surge unless you A: clean the battery ground or B: give the injection pump/tps its own ground to the chassis/block.

The correct thing to do would be pull the PCM connection and replace the ground pins.

A good solid Grounding System is a must for overall proper operation.
EFI and Electronic Ignitions need full voltage from the alternator and to get full voltage there HAS to be a good ground.
Don’t think Dodge is the only one with poor grounding systems, all vehicle manufacturer’s are cutting cost, so one or two deleted ground straps could save a lot.

IF you are not getting full voltage to any component or the truck isn’t running up to par because the ignition isn’t working correctly then consider at least checking the grounds or adding new grounds at critical points.
