Thought I might put this here for others to learn that haven't ever built battery cables since I remembered to take pics. I was taught by the guys at the truck dealership I worked at right out of tech school and have built tons of cables for semis over the years. Others might have there own or better ways. Obviously this bigger cable costs more but I had some leftover at work.
20170728_113739.jpg the crimper I like20170728_114110.jpg heavy duty adhesive lined heat shrink20170728_113927.jpg I always crimp then heat up with propane torch and fill the cable end with about a foot of rain core solder20170728_114151.jpgfactory size one compared to 2/0 new one 20170728_114927.jpgtools needed, nothing too spendy 20170728_114902.jpg 20170728_114615.jpg hopefully this will fit the starter fine. I bent a straight lug the inserted cable and bent and trimmed the end to get it right before adding solder. Once you solder it will wick up the cable enough that you can't really bend it too easily at the lug later on. 20170728_114917.jpg 20170728_164748.jpg Battery end, same thing crimp and fill with solder. 20170728_164801.jpg 20170728_114846.jpg stripped back about an inch or so20170728_113752.jpg 20170728_114950.jpg 20170728_114759.jpg I like red on the positive and black on the negative cables. 20170728_164840.jpg 20170728_114651.jpg 20170728_165303.jpg old and new. I put loom on my positive cables and tape every 12" . If the negative can rub I'll do the same with it. On this truck it just runs straight over to the alt bracket. 20170728_114913.jpg cable cutters I like. I think they are Kline but they sell therm many places. Work good up to 4/0 which is a little tough but rarerly used.
Thanks
 
I've had good luck using one of these type of hydraulic crimpers, then solder and shrink wrap.

I've made my own cable lugs out of copper tubing many times when I wasn't able to get any (like on a sunday ,when stores were closed around here in past years)...just flatten it with a hammer,drill a hole in it,crimp & solder it on...
 
good info. I need to build a set for my 6.2. Hell, both my trucks. The size difference is incredible. I bet the performance difference is significant also.
 
My pickup could probably use some new cables--they look original and I think they are the 4 gauge aluminum/copper type that weren't so great--long cranking periods in cold weather trying to get a balky 6.2 to fire up most likely cooks the cables and makes them get higher resistance and age & corrosion takes a toll also..

A few weeks ago my truck refused to crank,it would just "click" when I turned the key...feared the batteries had died,they were in it when I got it in 2003...but all it took to get it to crank was to grab the side post terminal on the passenger side battery,and move the positive one up and down,I guess it was corroded...

When I got home I removed all 4 cables at the battery and there was a lot of powdery green crap all over the battery post itself and the cables,and threaded hole where they bolt up..

I used a dremel tool and wire wheel to grind everything shiny again and what a difference,it now whips over like it has new batteries...(I am not expecting the ones in it to last much longer --its a miracle they still seem OK after so long!)..

Someone made new cables for my '85 6.2 Suburban before I got it--they used 1/0 welding cable by the looks of it--its twice as thick as the cables on the pickup and has fine strands--that seems to whip over a lot faster than my truck will,provided the batteries are fully charged..the burb needs to be cranked at full speed for quite a while before it'll start--my pickup is just the opposite--as long as it cranks fairly fast,it'll usually fire right up...the burb may have some cylinders with low compression I suspect..
 
Pretty much exactly how i make cables. Learned it from a rescue truck place i worked for a lifetime ago.

Piece of angle iron in a vise and a dulled rounded chisel for the punch works for the crimp. Usually takes extra hands. Hold the cable hold the end, hold the punch and the hammer.
 
To those that dont crimp, heres the rub.

If you get that cable hot, cranking on the engine, long winch pulls and so on, at some point the solder can reliquify and run out of the cable end. With the right adhesive lined heat shrink, you might be ok. Relying on the heat shrink alone to keep the solder in place till it cools and resolidifies, however, you might not.

The cucv im currently driving has this exact problem. You can tell there was solder there at some point but its all gone. Heat shrink has cracked and dried out. A couple of the cables were held together by hopes and dreams. Looking at the cables they seemed fine but little actual connection there.

To each his own. Ill always crimp.
