Make one, i wouldn't fit a second hand one no matter how good it looks.

Personally i have an array or cables and connectors from halfords because they came with the car, but i do find the 'Shark' branded battery terminal pretty good.

You can also get what you need from Pole Volt automotive supplies, or if you really have to, and can cope with poor customer service, then try Vehicle Wiring Products.

i would not use the replacement terminals shown in that link as they rely on two screws biting into/through the cable core,

Thank you all very much for your help here. Ile leave it to Malcolm as to what to do next but feel it would be a good idea to make one up myself.

Yes,the seperate terminals are the two screw type but the made up leads are crimped both ends.

Erm, i have replacement terminals that hold onto the wire with a single grub screw, and have never had any problems. I have however seen many failings where people have tried to crimp there own terminals!

You can always tin the ends of the leads to get a better grip!



As for VWP, i can only assume you've never called them, or simply haven't spoken to the miserable and unhelpful 'sales' rep that i have. When i'm putting in a £300 order i don't see any problem with clarification on a specific type of connector which was badly labelled in the catalogue, and I see no issue with asking for a lead time. Said sales rep seemed to think it wasn't worth dealing with me, was abrupt, didn't answer my two simple questions and eventually hung up on me.

Compared to Pole Volt, who has all the time in the world for even the most mundane questions, and will advise if he thinks something is missing from the order, on not required based on a description of the task, i know who i buy from! Infact the Pole Volt man has even contacted AMP/Tyco to try and source one of the stupid bloody connectors in the BX that no one sells, failed, but at least he tried!

the starter will be trying to draw about 70A through a heavey cable with the terminal held on by 1 or two grub screws,

not very satisfactory IMO,

you can buy battery terminals that clamp onto the cable core which are a lot better

I have foundthese type of battery terminals perfect for a quick and efficient fix for split BX battery post terminals as you can quicly cut off just the clamp bit leaving the intack soldered lug on the cable to bolt this new terminal over.
Here is a new one before fitting next to the old cut off lug from the one you can see fitted. I have some of these lugs available if anyone needs one.

You just have to file two little slots in the lug with a round file (red arrowed) to allow the bolts to clear as the lug is just ever so slightly too wide.

:) That's a neat idea - I've previously just shortened the cable and used universal screw terminals. Not that it's ever given me any problems though.

Not sure i see what the problem is? With the grub screw your compressing the cores of the wire onto the surrounding, getting probably ~30% of the braids contacting the surrounding. With the clamp arrangement you're getting more like ~20% of the braids in contact. In terms of current transmission I'd have thought the screw type connector are much better. The clamps i use have individual holes for multiple connections too meaning your not trying to cram several wires into one fixing.

If it's mechanical load that concerns you then i guarantee i can swing my weight off the grub screw arrangement, and if there is that much load on the cable in car, then your engine has fallen out!

I agree that the clamp method is a good arrangement, but i don't see that the grub arrangement is in any way worse in this situation. Personally i find the clamps too be unsightly relics, and only really a quick bodge solution.
