MrHellrais3R Posted January 29, 2014 Share Posted January 29, 2014 I wouldn't use a crimp end at all for grounds. There more of a chance that it'll fail. Large gauge copper end, fill it with solder and just shove the wire into it. Let cool, then shrink wrap it.

TheMonaLisa Posted February 1, 2014 Share Posted February 1, 2014 Due to the concern about not having the exhaust grounded, I decided to throw a 3rd ground on it for good measure. Tho I doubt it will be effective with the rust. http://img.tapatalk.com/d/14/02/01/ypegudaz.jpg Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Brian3676 Posted February 1, 2014 Share Posted February 1, 2014 A good crimp will be superior to solder. Vibration and movement are not good for soldered joints. A lot of people don't realize this and actually think solder is better. Look on a factory car harness, not one solder wire joint, look at aircraft, commercial and military, not one solder joint, all solid wire or crimped. It goes as far rockets, my grandpa used to be a engineer at NASA and every wire joint (although 99% are one strand from end to end) the few that are connected and crimped.

Andyjo Posted February 1, 2014 Share Posted February 1, 2014 Yup all of the aircraft work we so is crimped. Also, if you're attaching to an exhaust manifold, or heat shield there is an opportunity for the solder to melt (depending on the quality of solder and heat resistance it has) Link to comment Share on other sites More sharing options...

One thing for folks to keep in mind is that the crimp needs to be done correctly and with a quality crimper to assure a solid connection. I use Kline crimpers myself. Once crimped, if you put the connector in a vice and try to pull the wire out using vicegrips, the wire will break before the crimp fails. I like to cook my pets and my family. Use commas.

We have a few very fancy ones where I work I use sometimes also. Another thing that helps is to heat shrink wrap the connection, but use the heat shrink that has the adhesive sealant in it that activates when you shrink the tubing. Helps keep out every bit of moisture and corrosion. Posted pics below with a correctly crimped and wrapped ground. Link to comment Share on other sites More sharing options...
lgtvf52 Posted March 30, 2014 Share Posted March 30, 2014 just for the sake of reviving an old thread, I believe this is the issue that I am having with my motor (grounding issues) and I know that I am missing a few of these grounds so I am hoping that tomorrow I can get all these grounds on and the motor will finally start again! thanks for all the pictures for reference!

aac0036 Posted April 25, 2014 Share Posted April 25, 2014 Posted pics below with a correctly crimped and wrapped ground. Is this as easy as it looks? Would a good hair dryer provide enough heat to shrink wrap it? Just strip the end of the wires and insert them in? ANy firther details would be helpful. Please correct me if I'm wrong, but it looks like all I'd need (per side) is: 2 yellow end thingies 12 gauge wire 2 shrinkable thingies I'm going to bring photos since I have no idea what I'm talking about. Simply disconnect battery to install? Much appreciated, thanks. Link to comment Share on other sites More sharing options...
Andyjo Posted April 25, 2014 Share Posted April 25, 2014 Don't need to disconnect the battery... Just don't do it while the car is on I think you'd want to do a higher strand count than just solid copper (someone can correct me if I'm wrong). Yellow end thingies = crimp able ring terminals Shrinkable thingies = shrink tubing, a hair drier should be good enough, or careful application of a lighter or blow torch... Or turn the car on and hold it next to an exhaust pipe Link to comment Share on other sites More sharing options...
discojon Posted April 25, 2014 Share Posted April 25, 2014 I used old 8 gauge amp ground wire and some solder less ring terminals. Heat shrink covers the ring terminal to wire connection.DC currents travels on the surface of the wires not through them. Thats one of the reasons stranded wire is used in DC applications. This should read " AC currents travels on the surface of the wires not through them." Thanks for the correction. Link to comment Share on other sites More sharing options...
Max Capacity Posted April 25, 2014 Share Posted April 25, 2014 Yea the heat shrink idea is a good thought. I make re-make my grounds and shrink wrap them. It's not like it cost me anything. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

MoD_Scotty Posted April 30, 2014 Share Posted April 30, 2014 I had the same issue, so I went and bought a cheap grounding kit off ebay. I replaced the corroded ground, and added about 5 more...all running straight to the neg battery terminal. $20 and super easy to install.

utc_pyro Posted April 30, 2014 Share Posted April 30, 2014 ... DC currents travels on the surface of the wires not through them. ... You're thinking of skin effect, but that's for high frequancy AC, not DC. DC will flow through the entire wire. Link to comment Share on other sites More sharing options...
Nolmers06LGT Posted April 30, 2014 Share Posted April 30, 2014 You're thinking of skin effect, but that's for high frequancy AC, not DC. DC will flow through the entire wire.

theflystyle Posted May 31, 2015 Share Posted May 31, 2015 Just did this replacement myself. I used some marine grade cables from Amazon and I am certain I wont be needing to ever replace them again.

Max Capacity Posted June 1, 2015 Share Posted June 1, 2015 Funny story, here at work I just got a phone call from an Electrical Engineer asking about what we used for a ground strap? I said, wait a minute, I know how to get that p/n. I came here, clicked on the link to NAPA from a few post ago and forwarded him the NAPA page.

skibum0203 Posted October 21, 2017 Share Posted October 21, 2017 Just discovered the disintegrated straps underneath on both sides of the motor. Anyone know what length each needs to be? From what i read on each side it should run from frame to head and possibly a 3rd from frame to exhaust manifold? Any help is appreciated, thanks!
