(now) Negative (and Positive) battery cables (pair)

Geez, I had to have a whiskey before I could work up the nerve to ask why two....why doubling up negative/ground cable(s)?

Okay, I got the groove and the buzz on....... so let fly.
 
on mine the neg would not do the job (just not good enough) so i added an extra.
i think that if Mittzy wants to make us some it will work out great

Because Triumph used the minimum size wire that would work, not the optimal size.
