so I have not been able to ride my bike at night because I kept blowing lightbulbs. Troubleshooting led me to test everything from start switch completely torn down to the hi/low selector also being taken apart. Chased every yellow wire from alternator. One thing I should of realized from the beginning was that the 18 volts at idle was not a good thing but it took a lot of google searches for me to figure that out. So yes at idle I was getting anywhere from 15 to 19 volts. Any type of revving was giving me 18-20 volts and it came down to the regulator rectifier. Well thank god I have a spare 2009 Honda CBR 600rr. Took it off and trimmed the 3 yellow wire tabs about 1mm each and plugged them in. I know its a lot bigger then stock but I have a 2004 Yamaha R1 subframe so I have room to hide it in.
Yeah I read all that but why use an r1 rr when I have a Honda one. I saw the VFRness but no thanks. 100$ for 3 wires and a fuse. I still have warm wires but already started to make my own VFRness.
so I have a parts bike that I can cannibalize parts off and I did. Its all the same colors. So what I did was cut off the plug from the original R/R plug in all the wires respectively. I had to trim the 3 yellow wire spades but the power and ground fit perfectly. another shot I used this type of RTV because I have had it for about 5 years and it was free. pack the plug with as much rtv as you possibly can once you got it packed with RTV then you slide the old factory plug up and in place and let the RTV dry over night I also made my own version of the VFRness but didnt take any pictures because well I just didnt think to do it.
