I was getting almost a full volt.
The flow chart says anything over .2v is a bad connection between the Regulator, ignition switch and back via the switched 12v input wire. Wonderful... If I recall correctly that thing runs the length of the bike up to the controls and back through the headlight and gauge cluster en route to the battery (+). Whew.
My immediate question is: If my wife rides the bike in this condition will it eat another battery or harm the stator/RR in any way? From my limited electrical experience it looks like the battery is just getting a little more charge than it normally would because of some kind of fault or impedance in the circuit I mentioned earlier.
It doesn't matter where the actual wire goes you can ambush it..there are only two things it can be stopped at..the 30a fuse and the ignition switch...
get a yard of wire with a crock clip on each end, measure the resistance of the wire to make sure the clips are good..it's no good working with faulty tools..
The black lead from the rec is the switched wire, it joins to the red/white wire via the fuse and ignition switch..
locate the 30a fuse and look at the two wires that attach to the fuse holder, link them one at a time to the battery + measure the resistance if the fault is corrected remake the fuseholder connections clean and retension the fuseholder, measure across the fuse and if good clean the contacts and refit it, if bad replace it..
If that is all good you have to follow the instructions on page 21-5 of the Honda manual shop manual to check the ignition switch..
