Joining 25mm 170 AMP Battery Cable
#1
So I've got my cable, circuit breaker, terminal clamps and cut off switch for the Datsun.

How can I join the existing live to my cable safely?

I kind of want a clamp like on the terminal clamp but just for joining wires.

I've typed a few things into eBay/Google but can't find what I'm looking for..

Heavy duty crimps?

Any suggestions?

Get appropriately sized crimps. Crush them with a vice (unless you have hands like the hulk lol ) and then slap some solder around the wire to the crimp. Belt and braces Smile

or bolt them together if you're feeling cheap and cover in electrical tape

It took me a while to work out those words too! They seem to cost more than you would expect!

Thanks Cully, best get some tape too, don't want those big chunks of metal being exposed!

Edit: Less and cheaper:

Don't expect to do the ground with just connecting it to the chassis - seen it, tried it, never works, engine will crank insanely slow.

You *need* to run a +ve and -ve cable from my experience.

and its almost guaranteed to be better if you have a dedicated negative connection from engine to battery

well, quickest test, grab a jump lead. clip it onto the starter mount, and 'tother end onto battery.. if it improves, you are onto a winner..

i have a 600amp cable running from negative terminal to the top of the alternator bracket (one that bolts on by the fuel pump)..

that, and tightened the dedicated one on the back of the engine and it starts like a boss now

Or maybe get one of these?

And some decent crimp on ring terminals?

But surely if battery has a good ground to chassis, and engine has a good ground to chassis then there should be no problem? Never had an issue tbh.

Correct you are sir. People get slower cranking cars when they relocate the battery because of two reasons. Either their short earth strap is not on a clean enough surface (does need to be bare metal!) or the ring connector they have used isn't big enough or they haven't factored voltage drop when sizing their + cable.

I already have one of those, plus a circuit breaker, plus cable.

Well all that lot isn't going to help issues as it will all be adding resisitance

I don't see why some people are so negative about it? It'll be fineeee!

It's just a simple relocate battery from behind passenger seat, where it currently has a cut of switch wired to the positive(+) and the negative(-) straight to the floor pan to the boot where it will have an added circuit breaker and another 1.5m of cable.

Happy dayssss!

So I have my 25mm cable, I have the big crimpy things, how do I join them together?

Crush them with a vice?

Do I need a beefy soldering iron? Any suggestions, links to eBay products etc all considered helpful.

Here's the connectors I bought:

you need a heavy duty crimper for 25mm lugs
or you could solder the cables in

[attachment=18030]

this is cheap compared to what i paid for mine

A proper crimp tool like the one above is what's needed for a decent connection, avoid solder as much as possible, it can cause the cable to break due to vibration hardening. There are cheap tools available where you but the tube connector in a v shaped indentation and then force a wide punch into the tube, either via a vise or a Mallet.

Interesting argument over crimp/soldering.

Some wont ever do any soldering in a car due to vibrations/heat etc...

Then others wont do anything BUT soldering!

With my experience of french electrics and crimped things coming apart....I always solder or where I can, both.
Wishes for more power...
