To me the most interesting part is that (apparently) the losses, and not some design change or defect in the R/R its self, are what caused the lower charging voltage ... or said another way, the R/R really WANTS to charge at 14.x volts but is being inhibited from doing so by external factors...
We have been doing this on the DRZ400 at the TT forum.....for a while now..... It is a real thing..... Well.. we only messed with the wire from the RR to the battery, but gained about 0.3-0.4 volts...... I can see doing this on the ac side....even though the ac travels easier than dc does.... Interesting..... Lemmethinkaboutthis....... I might jump on this and try this.... But I need to get my new meter first....and listen what Joel thinks regarding enlarging the hole here.... He can do the math....backwards and forwards...before I can pull a double shot of espresso.....
(ps).... here is a link to the Thumpertalk forum.... scroll down to the "free power mod"..... they list 0.5 volts gain... I saw 0.35..... So it works.....
