Doing the hotwire mod and have a question
Written by mfmarkart on 10/20/2010 at 12:32 pm

I decided to do the reverse and change out the R/R, go for a ride and get
results, then do the mod. Well the new R/R is installed (no mod) and I'm getting
some curious results. I now have the dreaded upside down voltage issue to some
degree. I rode 35 miles in to work this morning. Idles at 12.9v. when I'm doing
15mph, it's 14v, 25mph 13.8v, 35 mph 13.6, 45 mph 13.5, 55+ 13.4v and holds
steady. So at least the problem I was having with the voltage dropping and
staying at 12.4v seems to be fixed for the moment. I think I need to put on some
more miles to be sure. The 13.4v that it is currently holding at is .3v lower
than I used to produce with no additional load. The 13.4v would not be enough
for me to run high beam (.1v), radar detector (.1v) and grip heaters on high
(.5v), leaving me at 12.7v at cruising speed. I'm going to finish the wire mod
tomorrow. I pre-wired it to the battery and starter solenoid while I had the
seat and body panels off. I'm thinking of cleaning and greasing the grounds that
I can find while I'm at it. I know the main ground is by your right calf while
riding and I can find the fan ground. Any others I should be looking for? Mark

on working on the mod tonight. My Chinese R/R is at the post office, picking it
up tonight. Will complete the mod first and test, then I'll replace the R/R.
I'll post the results. Mark
