Following on from my recent rambling I have now sorted out the relays so that they illuminate the correct parts of the bike... but with power coming from a cable attached directly to the +tive of the battery which is clearly not a long term solution... especially as I only have the one cable which would mean to go from dip to full would involve stopping and pulling the cable out of one relay and into another
So, to the nub of the matter... and my question.
Where do I take power from? Can I take it from the existing feed? I.E. The cable that delivers the power to fire the relay (say, full beam) is rated at 15A, can I simply bridge it from the switch over to the power and thereby when I hit the lights, the existing power cable both pulls the relay over and supplies the power to the new lights... or will it go bang as there's too much current going through the wire?
Help me obi-wan-kenbateman... you're my only chance.... which isn't encouraging to be honest
