Re: CBR 900 Regulator Issues
The Honda manual says to check the voltage output at the battery, not at the stator connector. That's what had me saying holy cow.. getting 50 volts at the battery. And it still seems high to me to be getting 50 straight off the stator.. why so high when it just has to be converted down to 12-15.5 volts?? Maybe someone else has an answer to that ( my ) question?
Check your stator by checking voltage AT the battery. You should get 13-15.5V/5000rpm. This is if you have a good R/R i believe.
Second: Remind you this is all straight from the horses mouth ( Honda book )
Remove the three prong connector that goes to the stator.
Measure the resistance between each yellow wire and (-) Ground for NO continuity. If continuity is present the stator needs to be replaced.
The standard GOOD measurement is 0.1-0.3 Ohms ( 68F-20Celcius temperature of the stator. if it's outside of this spec then replace the stator.
I'm really thinking your stator is fried. There's no reason to be blowing out R/R other than a bad stator OR a bad ground to the stator OR a bad battery ground cable. The only other explanation i can come up with that is just a theory, is a hot wire grounding out on the frame or engine.
While you are doing all this electrical sorting.. check your battery cables to make sure there is no corrosion on the cables themselves. Many times corrossion sneaks under the cable insulation and then starts rotting through. Replace cables if corrosion is present. Also on the subframe where the R/R bolts up to, replace the bolts and nuts of they are corroded, make sure they are tight and that the R/R metal backing plate makes good contact with the subframe. This is one of the issues that can make a R/R burn out.
