ok so i have a analog volt meter on my bike and a while back i was seeing readings of 13.5 to 14 volts while running down the road
and now im seeing 12.3

the only electrical thing i have done is to move blue wire in harness bypassing headlight relay as my light wasnt working

i tested the volts on the batt and i have
12.2v just sitting
12.4v at 4k rpms

im not sure where to go from here but im afraid the stator is going

any ideas??

It takes 13+ volts to maintain/charge a 12 volt battery. 12 volt is minimal and should be 12.7 volts on a fully charged battery. SO, what I'm saying is at 12.4 you ain't charging. Test the stator at the connections behind the engine and if all goes well move to the R/R. Could be bad connection at the r/r.

Try un-doing what you did, moving the blue wire back to where it was and re-test, Just a thought!!

firsttests=

i put the blue wire back in stock position and
key off = 12.47v
at idle= 12.37v
at 4k = 12.56v and slowly climbing


did headlight relay bypass and
key off =12.5v
idle = 12.18v
4k = 12.3v


i figured the v would be lower as now the headlight is on

leg b = .5
leg c= .6

ok 3rd test
stator ac voltage

at idle legs
a to b = 4.54v
a to c = 15.45v
b to c = 16.5v

at 3k legs
a to b= 9.39v
a to c =42.2v
b to c = 40 .8v

uh oh!

retested and results are consistant with the first time maybe a v or 2 off but still one leg is super low
