Halfords Battery Cables ? Body Earth Mounting?

[cjhillman]

I'm going to replace the Battery Cables to try and aid starting (bought a big Yuasa Battery for me Capri). From a previous post I was told to get to get heavy duty 80 mm sq cable. Turns out Halfords stuff is about that and has anyone used there stuff for replacement classic leads? Can't see there would be much difference.










Also thinking of moving the Earth back to the suspension turret (factory place) compared to the slam panel where it is now. Would there be any benefit? I heard that its best to have the Earths nearer the Starter Motor to help starting but I don't know. Plus does it always have to be bare metal?

You need it to bare metal - paint doesn't conduct electricity very well.

Engine earth just needs to be firmly secured - but it won't harm it if its under a starter mounting bolt.

Same for the body earth - secure and good contact. If its not, then anything else connecting the two starts to act as the earth - accelerator cable, choke cable etc - and they tend to get a bit hot and fed up under starting loads!!

i would personally always over earth cars i build , i always use a nice fat cable my local start alternator shop always sort me out there its double the size of halfords cables, good clean earths and double earth the engine block too is always a good thing so it wont earth out your acc cable or choke.. ive been there and it isnt a fun feeling or experience when driving lol...

those red cables in your photo are 16 sq mm, as shown on the cable lug. 80 sq mm sounds like overkill for a car to me.
