Evening all,
I’m swapping out my flat bars for pull backs and extending the cables to suit. There’s 8 cables on the left side. 4 have 9 strands each 0.3mm thick which is great because 5amp cable at Halfords (uk generic auto parts store) has exactly the same number and size of strands. However the other 4 have 16 strands at 0.3mm which doesn’t match the 8 amp cable from Halfords which has 14 strands at 0.3mm. The next one up is 17amp which has 28 strands at 0.3mm. My generic motorcycle wiring book recommends 28 strands at 0.3mm thick for headlights. My question is which cable should I use? 8 amp and not worry about it being 2 strands less or the 17 amp.
The down side of the 8 amp is presumably it might get slightly warmer which worries me a bit given the proximity of the fuel tank, and the downside of the 17 amp is the lights might be a bit dimmer? Any thought would be much appreciated
Regards
Tim

Hi Dave
Thanks for your response and formula. 8 it is then. I’m going to set myself the challenge of learning basic bike electronics this year - I feel I should have been able to work this out!
