Wire insulation chafing. More Protection Required?.


Go to solution Solved by Mike Self,

Recommended Posts

I am in the process of running some weld on tabs to hold my wiring in place.  I am running the battery cables, and I am worried that these tabs may wear through the wire insulation. Here is a pick of the wire.  And the tab.  Do I need something between it? The thickness is 3.4 mm.

 

I was thinking of putting some mesh protector around it. 

 

Thanks in advance

I’d put some piece of hose in between. I’m not a fan of mesh sleeve. While it looks nice at first it cumulates a lot of dirt and is pig to clean. Offers minimal protection.

The wire bundle tab surface should generally wrap around the wire. You want surface to surface, not surface to edge contact.

 

You’re not looking to run your wires thru those rectangular holes where it’s ’all edges’ in contact with the wire are you?

I am trying to picture how these work. Those tabs look nice (off the shelf from somewhere?) but I can't tell exactly how they will be used. Does the wire run parallel to the orientation of the tabs and you use zip ties between the two as a hold down?

Yes they will be running parallel. The zip tie will go through the big square hole, around the wire then through the opening between the welds back around. 

Here is a pic.

I really like these things.  I use a "helping hands" electronics stand to hold the tabs exactly where I want them.

Easiest solution:  go down to your local hardware store or Lowes Depot and buy a foot or two of clear (flexible) vinyl tubing  whose ID is the same diameter as the cable's OD.  Cut off an inch or two slice, slit it with a box cutter, wrap it around the cable and then secure cable and sleeve with a zip tie.  Project complete...

Those tabs are pretty cool. I wish they were cheaper but I can understand that's probably what it costs that small company to make those and turn a profit. I will probably stick with @D.martijn's OEM style clips if I end up ordering something.

Where exactly? Externally, like along one of the inner rockers?

Inside the car, along the bottom of the transmission tunnel from the back seat to the front.

I've run my positive cable from rear battery mount along the factory route and then nicely through a grommet through the firewall near starter for over 45 years with NO problems . The tubing cover where it passes through something.

Your first step IMO is to include a fuse at the battery, your wire looks like welding wire which has a robust jacket on it but safety first, as Mike said a bit of hose say a inch or so on either side of the pinch points will prevent the jacket from contacting any thing sharp and you'll sleep better at night.

These are very cool. I kept those in the car. I would have perhaps pursued these but they won't fit the 0 gauge wire.  The other ones will accommodate all wire sizes.

Dont use the woven sheathing stuff there, use the the vinyl tubing like Editor Mike says. That or chunks of old garden hose.

So thats a lot of white and blue cables hangin out there in the pic, you've piqued my curiosity Dude...land😉

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
