having just put my new mini starter on, I now need to lengthen the cables to it from the battery.
As all the wires on our cars are AWG, what do you guys use in metric equivalents (for say 4 ,6, 8, 10, 12, 14, 16, 18 gauge wires)?
Specifically, I am curious about the 6 and 12 gauge wire. I am supposing fatter cable is better for the main positive feed.

my thoughts :a heavier cable it always the best idea

Big fat flexible multistranded double insulated welding cable is the way to go.

decided on part ref; 010603 Flexible 315/0.4, 40mm2, 12.0mm, 300A for the battery cables. Manual says cranking amps 165-180A small block, 180-200A big block. Thought I would go one step bigger than the 010602 Flexible 196/0.4, 25mm2, 9.8mm, 170A as I`m lengthening the cable.
For the solenoid cable, 010104 44/0.30, 3.0mm2, 27.5A - cable OD 3.7mm. Should be more than man enough for the job.

just an update on the outcome.
New FAT cables fitted to starter motor. While I was being all electrical, thought I`d put some headlamp relays in. I reckon I `ve got at least another volt to the lights at idle. Certainly seem a lot brighter and it takes the load away from the headlamp switch
Also got all the new ignition parts and distributor on as well.

I am impressed! Very impressed.
I hope to sort out the whole electrical system on my car because it is pants!

Did you get the headlight relays from the same place as the battery cables neil?

yes, ordered everything through these guys and couldn`t fault the service.

I also put a junction box under the battery tray (less visible) to supply the relays.

Neat job. Simple to fit headlamp relays, much more difficult to keep the wiring nice and tidy.

AWG to sq. mm conversion ...
