16mm2 is around 110amps and as the starter on a petrol engine T25 can draw between 125 - 160 amps then 16mm isn't heavy enough......on a Diesel the starter can draw over 190 amps.

Therefore the braided earth cable needs to be 25mm2 on a petrol (170amps) and even heavier on a Diesel (30 - 35mm2) (205 - 240amps) ...these are rough guides.

This looks pretty good, no rating but looks heavy enough for a petrol:

bugger, bought a 16mm strap!!

fortunately its too long, so looks like getting doubled up!

going to drill a new hole and use a TEK screw to get a good connection as well.

cheers guys

Heard "kevtherev" read out on Absolute Radio the other day for their "haven't heard it in ages" thing they do. Requested a song by Simple Minds. Was it you? Didn't here if you rang in time though.....
