Voltage reading

[saige]

yea,trust me,i know the feeling,i have to do the same thing to my bike.
wasnt charging,than all of a sudden,everything comes back to life.i try and go thru the wiring once every 6 months.
so now i have to chase a gremlin.but i do need a new R/R.i dont have the mosfet one.

Thats def a R/R. Could be stator, check stator wires and they should all read around a certain range. Connect one wire to other with + and - on DMM, DC voltage (forgot if its DC or AC)? should be ~30 something at idle, ~50 or so when reving at 5k. If one of the wire connections is way different than the rest then its your stator as well.

I just read on a cbr forum that when this guy installed the same alarm his bike shut off like mine did.....im yanking this p.o.s off and see what my volts read

any good results from taking the alarm out.

[ZxSixxeR]

Took alarm out and when i slightly rev it goes from 12.1 to 12.4 checking rectifier now and what wires do i check? It is a mosfet i believe since it has fh uploadfromtaptalk1340038312076.jpg

Plugs arent melted or burnt at all it looks really clean.

yes,it is a mosfet.
i beleive yours has 3 yellow,one red and one black.i would have to see the plugs.
some is 5 wire,some is 6,not familar with this wiring.

thats a real good sign,doesnt mean R/R isnt bad,but atleast now you know its all good.
how many wires and what colors are on the R/R

[ZxSixxeR]

There are 3 yellow on one plug and red and green on the other then 3 green grounded to frame with a little corrosion

did you rev it above 2500rpms,i think it suppose to be up to 4000rpms to get proper reading.

ok,the yellow is for stator and charging,red is positive,green should be ground.
clean the ground contacts just for good measure.
on the link i posted earlier,should help you to know the ranges of the tests,or atleast someplace in that forum.

I put positive on all three of the prongs for yellow and they all came out to .5 with bike off?

this is what is says for inspection,did you follow this.
INSPECTION

1. Remove the left middle cowl (refer to section
3-8 of the 2004-2007 CBR1000RR Service
Manual).
2. Remove the wire band, and disconnect the
alternator 3P (natural color) connector.
3. Check each yellow terminal (of the
alternator side connector) to ground.
There should be no continuity.
Also, check the resistance between the three
yellow terminals using a circuit tester.
Standard: 0.1 – 1.0 ohm (at 20° / 68° F)


• If there is no continuity to ground on any
of the three yellow terminals and the resistance
is within specification, there may be
another problem. Proceed with normal
troubleshooting.


• If there is continuity to ground on any of
the three yellow terminals, or the resistance
is not within specification, replace
the ACG with the countermeasure parts
kit. Go to the REPAIR PROCEDURE and
PARTS INFORMATION sections of this
Service Bulletin.

ok i kinda know this one if i may... you going to need a muti-meter to check R&R. the R&R is just diodes soo if you put your muti meter to check for diode mod and then reverse it should say OL for open line do this for each prong going into the R&R do it one way and then reverse it it shoud have a reading one way and ol the other

[ZxSixxeR]

Ok so i left it running long enough for the fan to turn on and it was about 20 min and the voltage dropped from 12.3 to 11.5 revved it to 4k rpms and it went to 11.6 even holding it at 4k rpms

I put the multimeter on ohms and put it on the plug going to bike and it said. .5 on all three

ok,and it read the same thing with the bike off im assuming.

[ZxSixxeR]

Yes

Wait no when i turned the bike off it went back to 12.2

thats probably from your battery,im trying to find the manual so you will have all the instructions and specs you need,but its a little harder to find than thought.
