elkootcho Posted February 8, 2015 Share Posted February 8, 2015 When I was under that truck replacing an o2 sensor I noticed what appears to be a ground wire that has frayed and is no longer connected to anything. Does anyone know what this is so I can replace it? Link to comment Share on other sites More sharing options...
k9sar Posted February 9, 2015 Share Posted February 9, 2015 looks like a ground wire to me. probably runs to the exhaust system Link to comment Share on other sites More sharing options...
01Pathmaker Posted February 9, 2015 Share Posted February 9, 2015 That's a ground strap Link to comment Share on other sites More sharing options...
Precise1 Posted February 9, 2015 Share Posted February 9, 2015 X3 You can make your own out of some heaxy gauge stranded wire, but it might be challenging to find a place to tie it off to on the exhaust, it looks like the bolts are pretty rusted...

ferrariowner123 Posted February 9, 2015 Share Posted February 9, 2015 Why do they ground the exhaust again? For static? -Kyle Link to comment Share on other sites More sharing options...
01Pathmaker Posted February 9, 2015 Share Posted February 9, 2015 Not really sure why they do that, mine have rusted/broken long ago with no obvious ill effects. I wouldn't worry too much about them. Link to comment Share on other sites More sharing options...
k9sar Posted February 9, 2015 Share Posted February 9, 2015 There are electrical things attached to the engine that do not have their own body ground, thus there are several places where the engine and things attached to it are grounded to the body.

hawairish Posted February 9, 2015 Share Posted February 9, 2015 Redundant grounds are good! You'll know when your last one fails... B Ha, yep. I wouldn't worry about it much, but some other options include: --soldering or crimping the pieces back together; you should be able to curl the ends into a butt splice connector and crimp --soldering or crimping a new body-side piece to the existing exhaust-side piece --make a new grounding strap using wire, a ring terminal, and a hose clamp You should also be able to bend the ring terminal on the body-side, as well as rotate it, to give you a little more slack. The body-side bolt should come out no problem. As B mentioned, the exhaust bolt is rusted...wouldn't even open that can of worms. On a parting thought, that strap shouldn't break under normal wear and tear...I just noticed mine the other day by coincidence and there seemed to be plenty of slack, and everything allows for flex (hence braided strap vs. stranded wire for all other grounds). How are your exhaust hangers? Or do you think this just got snagged on something? Link to comment Share on other sites More sharing options...
Precise1 Posted February 10, 2015 Share Posted February 10, 2015 I'm betting it burned off, I've seen that before. The thin strands of the braid don't hold up to intense heat very well... B Link to comment Share on other sites More sharing options...
kdj Posted February 10, 2015 Share Posted February 10, 2015 Rust? That's now called "patina". Link to comment Share on other sites More sharing options...
Wifes96NP Posted February 12, 2015 Share Posted February 12, 2015 Don't worry about it. Since these trucks were built with way too much sheet metal as over redundant amounts of heat shields they needed to ground all this excess material as it can statically build up a charge and spark. If you don't drive through puddles of gasoline you are perfectly fine without Link to comment Share on other sites More sharing options...
CDN_S4 Posted February 12, 2015 Share Posted February 12, 2015 So you're telling me I have to stop driving through puddles of gasoline? Dammit!! 2 Link to comment Share on other sites More sharing options...
Wifes96NP Posted February 12, 2015 Share Posted February 12, 2015 It could also be an attempt for corrosion inhibition. Not sure if it was a success lol Link to comment Share on other sites More sharing options...
elkootcho Posted February 12, 2015 Author Share Posted February 12, 2015 upon closer inspection it appears burnt. Must have been resting directly on the exhaust. Link to comment Share on other sites More sharing options...
