maybe we're not genius as you when it comes to wiring etc.but i observed that it will be much better to put an SPDT RELAY cause it will served as an automatic on/off on fast charging rectifier specially on day ride.and ive seen so many mc just cut their yellow wire without using switch...the result is overcharge and now they need to change their battery...as i estimated,battery(depends on brand) range from 600 to 1k plus and SPDT RELAY cost only 100 to 150(d.i.y wirings).theres nothing wrong whether we put relay or just cut the yellow wire...its just assurance for peace of mind.always remember that prevention is better than cure...
we're sorry if our opinions make you laugh...but we dont have much budget if our battery or wiring goes wrong to fix urgently...sir thon is right,instead of laughing,why just dont you share your knowedge to our fellow t135 member...
