Fixing the 'Splice' for Improved Charging

For my Max, I saw the most gain in charging voltage by cleaning the footpeg mounting bolts = thereby better grounding of the 85 OEM R/R. I meticulously went through other connectors, rechecking idle charging voltage at each step. No step increased the voltage more than cleaning those peg mounting bolts.

And lets face it, IF the OEM black box were designed to perform on lower voltages, it really wouldn't matter how much charging were going on, as long as at minimum, it brought the battery back up to full charge for the next start, including taking care of the total electrical needs of the bikes' accessories like lights, turn signals, brake lighting, horn, and cooling fan.

Incidently, over this very weekend, the problem has recurred again for the first time in over 2 years on my bike. Rest assured, I will be taking it back apart at the footpegs this evening. I am going to look at adding a ground specific wire to the body of the OEM R/R this time. I also found my battery to be extremely low on fluid level last evening. Topped it off and recharged last night, but will finish my R/R inspection/mod this evening.
 
That crimp fix assumes that the poor charging voltage is due to weak positive which misses the point completely, the problem with max harness is the grounding, when I did this fix volt gains were negligible, less than 0.5 volts but after I did the RR direct connection fix volts went up to consistent 14.20 + volts.
it makes sense since all the stator out put is passing through the RR to feed the battery so connecting the red RR directly to +ve battery terminal & the black RR connected to a good grounding point on the frame NOT the -ve battery (you want to feed the frame with a healthy -ve to feed all other grounded circuits.)

How about leaving the black wire as is and running another black wire from the same spot to the v max cover .That way you have two neg grounds and a really good neg ground connection .I do not think sanding the back of the r/r helps .I tried this with no gain and with two black wires (one to the neg side of batt and one to the side cover should be a good connection.
 
Tried to solder this stupid thing again with a small micro torch and still no luck .I give up and taped it up .Why the hell didnt yamaha solder this thing?.
 
I just used my regular soldering iron. I have a few tips for it. I used the widest one in the kit. Held the tip against the crimp for awhile and waited for it to heat up. Then just touched solder to the wires on either side of the crimp and it sucked it right up.
