My charging system is only putting out 11.5 volts if i unplug the headlight i have 13.... book says i should have between 13.5 - 15.5. All my yellow wires from the stator going into regulatorhave 5.7 volts (17 volts) but i only have 11.5 comming right out of the rectifier it is new and so is my stator because my statorlast season shorted and lit the regulator on fire. The grounds are all clean for the rectifier got .001 ohmz when checked. Any other ideas? if theres 17 going into the rectifier shouldn't i have between 13.5 = 15.5 comming directly out of the rectifier? (red/white)

 

Did you go through the whole troubleshooting process? If not, here's a good link that's pretty helpful.

I have done all of that its going towards a bad rectifier but its literally brand knew thats why im confused..... all right resistances for alternator Grounds are perfect.

 

did you check the stator resistance at room temp or when the bike was warm?? Check at room temp. They should be .1-1 ohm
What is your voltage with the bike off?
Do you have any current leak?

 

make sure battery voltage with bike off is somewhere about 12.8v. Makes no sense that the bike would be reading anything below 12v unless the battery was dead.

If you are checking voltage output at idle, that is part of your problem. You need to rev the bike to like 5k and check voltage. You should have 14.xx at that point. At idle you RR isn't going to charge the battery. (according to the tech manual, it will charge at a 1 amp rate at 5k rpms.)

When you first start the bike it should crank like a wild man, if it cranks slow then your battery needs a charge or is bad. -should read 12.8 at rest, but not go below something like 11v even while cranking. I had a battery last year that I though was good but the bike cranked slow and I found under cranking load it would hit 8v, which won't get me hardly any spark.
