Crimping tools help
I just have asked on here before spending my cash.
I have a crimping tool for those red, blue and yellow terminals and that is pretty easy. But I wanted some non insulated terminals to fit into relay
holders etc. So I bought this
Crimper
And a load of these
Terminals
I was expecting something different and it doesn't seem right. Have bought the right tool? If so how is it used? If I have not bought the
right tool then what do I buy?
Cheers

Think thats the wrong crimper, I use long nose pliers and a Soldering iron.
Squash the ears down to hold the wire and then solder it on

Just remember to slide the protective sleeve on to the cable before attaching the terminal though! Done that a few times. I always solder terminals on
anyway. Looks neater than a crimped terminal.

There must be a automatic crimper for the terminals with sticky up 'ears'. I think I need this one
CBS CRIMPER very costly
So I have bought the wrong smegging one! AGGH!

Looks like the correct crimper to me, have you actually tried it on a crimp. Obviously you have to use the correct size dye and the crimp has to
fitted in the correct orientation. Give it a go !
I spent a lot of money on booze, birds and fast cars. The rest I just squandered.

I have had a little play and I just ended up with bent terminals. Bit boring really. Perhaps I shall have to fork out for the CBS one.

Hmm...
I would not use the non ratchet types of pliers.
I would not pay £25 / £38 for ratchet crimpers either, unless you are wiring cars for a living.
CBS arent the most cost efficient of suppliers
I have something like these:
Electricians Crimper Ratchet Crimping Tool Pliers | eBay UK
They are good enough for kits / home and occasional use.
As for Soldering, thats fine, as long as you have a good mechanical connection in the first place. Ie the tube bit of the terminal is crushed (Ahhh...
Err Crimped) first to give that good mechanical connection. The solder merely holds everything in place.
A well made crimp is the way to do it. Crimps have taken over form Solder joints for well over 25 years now in Industry.
I was taught how to solder over 40 years ago at the GPO (previous name for BT) training school, and spent several days stripping and joining wires
until it was perfect every time. (Old school and proper in depth training!)
The Instructor repeatedly said its the mechanical connection that carries the current, and the solder was to stop it coming undone / turning into a
bad connection.
The trouble with Solder connections in cars is simple.
1. The solder can crack with repeated or continuous vibration.
2. With repeated heating and cooling (say in the engine bay) the solder will stress and crack forming "Dry Joints" (Similar to the above).
My Volvo ABS unit suffered from this!
Crimping gives a solid and secure mechanical joint that will not come loose. You just need to use half decent ratchet crimpers so you get consistent
tension on the crimps.
Those £3 plier (Non-Ratchet) types do work. However you never get good solid crimps with them, and you end up getting weird little faults appearing in
a few years time, due to the connection deteriorating over time. ie not a solid crimp.
Its your car, and a good set of crimpers will last a lifetime, and you will use them more than just the once!
Have fun, and dont spoil the ship for a Ha'peth of Tar!
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.
Best Regards

I have a set of those crimpers you linked to but I thought that they were just for the pre-insulated type of red, blue, yellow fixings? I wanted a
set of crimpers for the non insulated types like this

PR4 from vehicle wiring products on this page but it's 29 quid. It is the correct one for the terminals you show. Mine is about 10 years old,
works very well, I don't solder them and have had no electrical probs with poor connections after 8 years on the road. I have had soldered joins
fatigue and break.

That polevolt one is the same and cheaper!

Not been through all the links but the ones you have are wrong for that sort of terminal. The one you want will have a large round hole (D shaped both
sides) to start the crimp and then smaller section thats W shaped groove on one side. That finishes the crimp by folding the 2 tangs in. It's
more fiddly than the cheap crimp terminals but a better job once done.

I use the MP71 for work every day, never felt the
need to buy a more expensive one.

A local DURITE stockist is what you need, 0-703-50 is what you want

and

Hope this helps.

Yes that is the correct one for the type of terminals that you have. The one that you already have is for fitting tube type teminals, type you would
have to fit on your battery. HTH Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

I have the posh ones (both types) also have the cheap and cheerfull one 40inches uses and must admit nothing wrong with the cheap one only problem is
you have to do each set of ears seperately, but with care you get just as good a finish.
